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'.

The brunette beauty is currently pregnant with her first child with fiancé footballer Wayne Bridge.

Sandford has joked that she's never been a wild child, but insists she could be less well behaved if she put her mind to it.

She quipped: ''I wish I was interesting enough to say I'd been arrested. Maybe I need to put more work into being drunk and disorderly; at least you get a good night out of it.

Sandford added: "Some people are so rude when we're out and I've never punched anyone, so maybe that's what I should do. People just want to take the p**s out of you in public to make them look bigger in front of their friends. Whatever happened to manners?''

The Saturdays - also comprising Mollie King, Rochelle Wiseman, Una Healy and Vanessa White - recently landed their first UK number one single, 'What About Us'.

Sandford thinks it will be a long time before the girl group top the charts again.

When asked how long she thinks the next number one single will take to materalise, she explained to Q magazine: ''I'll probably be 100 at that point.''

Writing on social networking site Twitter on Thursday (May 2) Sandford 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! (sic)."

She later posted a picture surrounded by her bandmates showing off her tiny baby bump.

It's been a month of big news from The Saturdays hitmaker as she announced her engagement to footballer Wayne Bridge back in April after dating him for some time, and she took to her official Twitter page a few minutes ago (May 2) to share the wonderful information:

"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! 😬❤"

A message was also posted from the girl group's collective Twitter page, which read: "Lots and lots of love to @FrankieTheSats and Wayne on their big news!! The Sats family is growing and we are SO thrilled for them! xx"

Her bandmate Una Healy, who is also a mother to one-year-old Aoife Belle (pictured below), congratulated Sandford publicly this afternoon and tweeted: "So happy and excited for our @FrankieTheSats and Wayne's baby news!! X"

The Saturdays' Rochelle Humes is also pregnant although she is due to give birth this month and it will be her first child with husband Marvin Humes, formerly of boyband JLS.

During an interview with Attitude magazine, the hunk explained that he had been lamenting his love live with an agent when The Saturdays appeared on the TV in the pub they were in so he pointed at her and said that she would be a great girlfriend:

"I'd been having lunch in a pub with my agent when he asked about my love life, and I was, 'Oh, non existent.'"

"He asked me if there was anyone I was thinking about, then The Saturdays popped up on the music channel in the corner, and I said, 'Oh, the one with the blue tights.' And the next thing I know, I've got a text saying, 'She's expecting your call.'"

The pair got married back in the summer of last year and now have a one-year-old daughter together named Aoife Belle.

The girl group are releasing the track 'Gentleman' as their next single, which is due to feature on their forthcoming new album.

The 'What About Us' stars have regularly teased the video, but they have now unveiled the full clip.

It sees the quintet spend time gardening before coming face-to-face with their male counterparts.

The five ladies can be seen in black suits with hair tied back, clutching gifts such as flowers and jewellery.

The pop group - comprising Cheryl Cole, Nicola Roberts, Kimberley Walsh, Sarah Harding and Nadine Coyle - called it a day after their final 10th anniversary tour show in Liverpool on Wednesday (March 20).

Fellow British group The Saturdays have expressed their sadness at the chart-reigning band's split.

The Saturdays singer Rochelle Humes told the Daily Star: " “It’s the end of an era. I went to see them on the Ten tour and I’m like: ‘Why are you splitting up?’ It was such a good show.”

Bandmate Una Healy added: “We supported them on their arena tour five years ago,” before Vanessa White finished: “It’s so sad.”

The Saturdays - also comprising Frankie Sandford and Mollie King - are currently making waves in the US thanks to their reality TV show 'Chasing The Saturdays'.

The girl group - who are on course for their first UK No. 1 single this weekend - are proud of their recent success.  

King explained: “We were filming last year for three months and now we’re promoting everywhere. A lot of people have asked us if there will be a second season and we’re like: ‘Oh my gosh – we don’t know.’”

The British group's last full studio effort came in the shape of 2011's 'On Your Radar', which charted at No.23 in the UK.

Speaking to Digital Spy, Una Healy said that they have finished working on their next album, which is due to be released later this year.

When asked about the record and its apparent title 'The Chase', Healy said:

"That's the working title, it's not the actual one. I think with the whole Chasing The Saturdays and chasing success, we'll call it that for now. But it's not the definite title. We'll have another single and then the album. We've finished it though."

The 'What About Us' singer revealed that a number of live shows are also lined up for 2013. When asked what the near future has in store, Healy replied:

"We have lots of shows in the pipeline. It's been over a year since we went on our last tour, so hopefully we'll get to do that again towards the end of the year. I'd love that, because it's my favourite thing to do."

The girl group are yet to secure a No.1, with the quintet coming achingly close in 2009 with the No.2 single 'Just Can't Enough'.

Speaking to Digital Spy, Una Healy said that she would to see their upcoming single 'What About Us' claim the top spot.

However, the singer remains cautious and is refusing to put all her eggs in one basket. She said:

"You'll always be hoping, but I don't want to count our chickens and get too excited. If it doesn't happen I don't want to feel disappointed, because we've got this far without ever having one."

The Saturdays star continued: "It would definitely be a cherry on top if we ever did get one. I won't put all my hopes on it, but I'll be very pleased if we get a good Top 10 position of some sort."

The group's new single 'What About Us' is released in the UK on Sunday (March 17).

Speaking to OK! magazine about being married to the sportsman, Healy explained that they rarely argue, but if they do it's usually because he leaves a mess all over the house they share: "We don't have massive arguments any more. But I get annoyed when I see clothes of his on the floor or he hasn't made the bed. If you don't know what I'm like, you might think I'm being aggressive, but he just laughs at me now."

She added that they're very different where organisational skills are concerned because she makes lists to ensure all of the chores are done, whereas Foden just won't bother: "I make lists. I say, 'When I get back you must make sure the bins are left out, because you know they're only collected every two weeks.' I come back and the bin is overflowing. The Christmas tree is still in the back, it's an eyesore."

Foden gave his two cents on their domestic incompatibility and joked: "I give her a bit of grief because she's so stressed about everything. We'll have a day off but before we relax she wants to do everything off her mental list. She's very organised and motivated, whereas I'm lazy and messy! Chalk and cheese."

Watch The Saturdays' interview on ITV's Daybreak here:

The pair's relationship was under scrutiny recently after an Australian waitress claimed she bedded the singer in London.

Malik and Edwards were said to be on the rocks, but it seems all is well after the couple visited an outdoor zoo in England together earlier this week.

British girlband The Saturdays - who are friends with One Direction - say they feel for the high-profile couple in the wake of the scandal.

Rochelle Humes explained: "They're gonna get that. Sadly it comes with the territory and that's one of the downsides," before Frankie Sandford added: "I feel quite bad for them. Perrie and Zayn, considering One Direction are one of the biggest boybands in the world and Perrie is in Little Mix, you don't actually know much about their relationship. You feel a bit for them.  It's out of their hands."

The Saturdays - also comprising Mollie King, Vanessa White and Una Healy - are currently promoting their reality show 'Chasing The Saturdays'.

Sandford has laughed about watching herself on the small screen.

She admitted to Heat radio: "It's one thing watching yourself while you're performing - that's awkward enough. But watching yourself just being you and forgetting the cameras are there it's just weird."

"I'm so much more common than I think I am in my head!"

The British group recently premiered new series Chasing The Saturdays in the US as they document their bid to crack America.

It debuted in the UK on Sunday (February 3) but Healy told The Sun that she doesn't really know audiences will take to their personalities. She said:

"I can't understand how anyone will find us interesting - it's just us. But lots of people want to be pop stars so it will show what life is like in a pop group, how we have bad days and get upset. Yet I think our friendship shines through."

Bandmate Mollie King added: "When we sat in the first meeting with E! pitching the idea of the show, we told them we were like a family and really got on. I think that's what people want to see - not five girls bitching. They followed us for three months and were surprised how close we were. It's us against the world, not against each other."
