The star's hit single 'Baby', which has gone 12 times Platinum since its release in 2010, has been named the highest certified song in American music history.

The 'Boyfriend' heartthrob has now beaten Elton John's double-sided 'Candle in the Wind/Something About the Way You Look Tonight,' which went 11 times platinum back in 1997 and previously held the impressive record.

The recent change made by the Recording Industry Association of America, which incorporates on-demand streaming data when it comes to measuring gold and platinum success, helped Bieber in reaching the feat as 100 streams is now considered equivalent to one download.

The Saturdays star brought girl Alaia-Mai into the world this morning (May 20).

Husband Marvin Humes confirmed the news via Twitter this afternoon, revealing:

"This morning we welcomed our baby girl Alaia-Mai Humes..Mum is doing great & baby is amazing! We are both overjoyed! Thanks for your love x."

The Saturdays tweeted: "MASSIVE congrats and lots of love to @MarvinHumes and @RochelleTheSats on the birth of Alaia-Mai! We can't wait to meet our new niece!! x."

Frankie Sandford meanwhile will be the next Saturdays member to give birth, with the singer announcing the good news earlier this month.

The two stars will be reunited with Adam Levine and Blake Shelton on the judging panel of the hit TV talent show.

In a statement, Paul Telegdy, President of Alternative and Late Night Programming said: "We locked in a plan several months ago to have the outstanding Christina Aguilera and Cee Lo Green rejoin Blake and Adam for cycle 5, and we're pleased to announce that the original four coaches are going to be back together in the fall.

"They're the reason this show was launched so strong for the first three cycles and we owe them a debt of gratitude."

Aguilera and Green were replaced by Shakira and Usher on this season. The two new mentors will return to the show for cycle six.

Telegdy added: "And after careful consideration of everyone's schedules for next spring, we are excited to be returning the current cycle of judges -  Shakira and Usher along with Blake and Adam - for cycle 6, which will premiere after the Winter Olympics."

Shakira recently revealed her desire to take time off from the show to spend time with her baby son.

She said: "I'm not going to be able to do next season because I have to get back to my motherhood and also get back to the studio, the recording studio, to finish my album, the one that I started working on before I had to deliver a baby and before I took this gig with The Voice. So yeah, I have to take a little break. But you never know, I might come back!"

NBC Entertainment Chairman Robert Greenblatt gushed about the opportunity of having all six stars on The Voice US.

He said: "We're very fortunate to have these six incredible artists to weave in and out of the show as their performing and recording schedules permit. The show has taken off largely due to the rapport and commitment of these great coaches, in addition to the expert hosting of Carson Daly."

The site revealed that several official sources confirmed the exciting news to them today and this information comes just days after the 'Halo' beauty was forced to cancel a concert in Belgium under doctor's orders.

While she cited dehydration and exhaustion as the reasons for the cancellation this week, many news sites ran stories suggesting she could be expecting another baby and E! now appears to have reinforced the speculation.

During her live show on May 15, Beyoncé told the audience she was also advised to call that performance off but decided to go ahead regardless as she didn't want to let her fans down.

At the MET Gala in New York earlier this month, she raised eyebrows after walking the red carpet in a custom-made Givenchy gown (pictured below) with a belt that covered her stomach. Pictures have also been taken of Beyoncé over the past few weeks at her Mrs. Carter gigs that show her with a more rounded stomach than usual (see above left).

Frankie Sandford meanwhile will be the next Saturdays member to give birth, with the singer announcing the good news earlier this month.

Marvin and The Saturdays singer Rochelle are currently expecting their first child together, with the beauty due to give birth any day now.

Humes says he is getting impatient about their impending arrival.

Speaking to Capital FM he said: "It’ll be any second now, so I’m on tenterhooks really. It’s all a bit mad. I cooked a jalfrezi for her last night but no luck yet.

“I need to try a hotter one next, like a vindaloo!”

It seems Rochelle is getting just as eager to welcome their new bundle of joy. The star took to her Twitter page a couple of days ago to write: "This is week is going sooooo slow!! (sic)."

Rochelle also used the social networking site last week to dispel rumours she had already gone into labour, tweeting: "Heard on Twitter that I'm in labour. Thanks for letting me know guys hahahahaha..I hope this is what it feels like cos I'm chillin...LOL :-) (sic)."

Meanwhile, The Saturdays recently premiered their latest single 'Gentleman' - the follow-up to previous chart-topping release 'What About Us'.

The superstar singer gave birth to daughter Blue Ivy Carter in January last year and as it is her first child, it's something of a learning curve.

Speaking to ITV's Daybreak, the 'Grown Woman' star revealed that she uses an anecdote from Canadian talent Celine Dion to help her keep her child happy. She said:

"I have a mommy voice. I keep my Beyoncé voice for the stage and I have my simple mommy voice. I remember hearing a story about Celine Dion and she was like, 'When I sing...my son cried'. And that's so interesting."

Beyoncé continued: "She has the most beautiful voice in the world and she's like, 'He hates it'. So I say, well, maybe I'll just give a little simple nursery rhyme voice to my daughter."

The singer meanwhile is currently on her Mrs. Carter Show World Tour, with her next date taking place tonight (May 17) in Zurich, Switzerland.

The sultry singer became a coach on the reality TV show late last year to replace Christina Aguilera.

However, she told Us Magazine that she will step down from the series in order to focus on her new child Milan, who was born in January.

Shakira added that she will also resume work on the follow-up to her 2012 album 'Sale el Sol'. She said:

"I'm not going to be able to do next season because I have to get back to my motherhood and also get back to the studio, the recording studio, to finish my album, the one that I started working on before I had to deliver a baby and before I took this gig with The Voice. So yeah, I have to take a little break. But you never know, I might come back!"

As previously reported, Shakira recently admitted her fear that boyfriend Gerard Pique might not find her attractive post-pregnancy. She said: "Looking at your new image in the mirror...I looked like a Shar-Pei when I first delivered. I was like, 'Oh my God. Am I ever going to be sexy again? Is my man ever going to feel attracted to me again the way he used to be."

The Saturdays singer is currently expecting her first child with JLS star husband Marvin Humes, and the pair can't wait to welcome their new arrival.

Rochelle - who is due to give birth very soon - took to Twitter today to share her pregnancy woes.

She wrote: "Got to sleep at 1 woke up at 3.30. #heartburn #livelybaby oh wow!! To make it worse @MarvinHumes looks as though he's having the best sleep! (sic)."

Bandmate Una Healy - who gave birth to her daughter in March last year - suggested Humes should be expecting a "hairy baby" because of the heartburn she has been experiencing.

The pregnant star responded: "I so remember you being like this. I now feel your pain x (sic)."

Humes took to Twitter earlier this week to dismiss speculation that she had gone into labour, tweeting: "Heard on Twitter that I'm in labour. Thanks for letting me know guys hahahahaha..I hope this is what it feels like cos I'm chillin...LOL :-) (sic)."

Meanwhile, The Saturdays recently premiered their latest single 'Gentlemen' - the follow-up to previous chart-topping release 'What About Us'.

During a new interview with Ellen DeGeneres, Shakira confessed that after having baby Milan in January she began to feel insecure about her body:

"Looking at your new image in the mirror... I looked like a Shar-Pei when I first delivered. I was like, 'Oh my God. Am I ever going to be sexy again? Is my man ever going to feel attracted to me again the way he used to be?'"

The beauty also joked that having a baby isn't as "idyllic" as people think because of the general mess of childbirth and the shock of delivering a "purple and wrinkled" baby:

"Delivering a baby is not as idyllic as people make it seem. Don't expect that he is going to be rosy cheeks, cherub when he is born. Actually, when I saw mine, I was like, 'Oh my God! He is purple and wrinkled. What is this?'"

The Little Britain comedian recently became a father with wife Lara Stone but Holden said on Alan Carr's Chatty Man that there might be a third party involved.

The Britain's Got Talent judge suggested that Cowell and Walliams may have mixed up their sperm together before the conception took place. She said:

"I said he looks more like Simon. They're going to make brilliant dads. I think they put it all in a test tube, gave it a little shake and Lara took it."

Holden also commented on recent reports that her colleague Cowell doesn't wear any underwear, revealing:

"He stood up, sorted himself out and I saw it dangling. I could almost tell what religion he was. I said, 'Darling, have you got knickers on?' He went, 'No, darling - I love to go commando. I like to be free'."

The singer gave birth to her first baby Blue Ivy Carter in January last year and it seems she's caught the mothering bug.

Speaking to the Mirror, the superstar icon said that her perspective has changed since becoming a mum, with her priorities shifting as a result. The 'Grown Woman' singer said:

"Definitely I would like to have more children. Motherhood has changed everything. You see things a bit differently after you give birth and my biggest job now is to protect my child."

She continued: "After giving birth there's a moment of rediscovery when you are making sure you still have goals and take care of yourself as a woman. That was something I struggled with - making sure I was still this strong woman and also making time for my child and balancing the two."

Beyoncé's next tour date meanwhile is a show at the Manchester Arena on Tuesday (May 7).

Writing on social networking site Twitter on Thursday, the 'What About Us' star confirmed that she is pregnant: "Some big news from me today! Wayne and I are having a baby. We are both SO happy and can't wait for his or hers arrival!"

Following her exciting announcement, the rest of her bandmates posted a message of congratulations via the group's official Twitter page and accompanied the well-wishes with a cute photo (seen below): "We can't wait to be aunties!!! Sooo much love to Frankie and Wayne -Mollie, Una, Ness and Roch."

Member Mollie King also revealed her excitement at the news via her own Twitter account, adding: "Soooo unbelievably excited for @FrankieTheSats and Wayney! Bring on the baba! Sats Juniors is really coming together ❤ xxx"
