The 'Moment 4 Life' hitmaker also took some time to answer questions from her 10 million followers and admitted that she will spend time "this week" shooting a video for 'Right By My Side', which features on her new album 'Pink Friday: Roman Reloaded'.

Although Minaj hasn't teased any clips from the video, stills from the shoot have surfaced (pictured below) and show her writhing around in the sand while wearing a hot pink bikini and sporting green hair. 

Madonna was due to kick off the extensive run of dates, which are in support of her fantastic new studio album 'MDNA', on May 29 in Tel Aviv, but has now been forced to reschedule the first show to May 31.

"Madonna's MDNA Tour is now planned for Thursday, May 31st at Ramat Gan Stadium in Tel Aviv, two days later than previously scheduled due to production delays."

"The change in the opening date was announced today by promoters Live Nation and Shuki Weiss. All tickets dated May 29th will be honoured at the rescheduled May 31st event."

However, he has now confirmed that the pair have worked on a "couple of things". He said:

In what is good news for those wishing they could hug Harry Styles in the privacy of their own homes, Hasbro have announced plans to bring out the dolls across the world later this year.

Chief marketing officer of Hasbro, Inc. John Frascotti said that the company is pleased to be working with such a globally successful brand. He said:

"In the short time since the group's debut, One Direction has captured the hearts of many young fans across the world.

Rolling Stone reports that the duo spoke to journalists via conference call on Wednesday (April 25), taking time to dismiss claims that they're on the rocks.

SkyBlu said that the reports are "completely false" and that they will always be close. He said:

"It's completely false. We're family at the end of the day. Blood is stronger than anything."

RedFoo meanwhile added that whilst they may break off to pursue solo endeavours, LMFAO will always be key to them. He said:

"Sky might be doing a DJ set in South America and I might be in Vegas, and they'll say, 'Oh, they're separate doing things. How can we make a story out of that?'. We have to be smart enough to recognize it's all a game, keep executing our vision and turn this world into a party planet."

The pair will be featured in the annual Sunday Times Rich List, with Cowell at No.7 and Beckham at No.10 as a result of her and husband David's combined wealth.

The list's top dog is record executive Clive Calder with an estimated wealth of £1.35 billion, whilst theatre producer Sir Cameron Mackintosh sits at No.2 with a relatively modest £725 million.

Other names in the list's top ten include Andrew Lloyd Webber and Mick Jagger.

Franco, who has appeared in such films as Milk and Pineapple Express, told MTV that she had requested that he appear in the video - which has been viewed on YouTube some 165 million times - but unfortunately he could not do it. He said:

"She actually asked me to be in that video, the one with the relationship that gets crazy. I couldn't do it. But, I guess, I hope that that means there's mutual love between us."

Franco meanwhile hinted that Rihanna could be set to return to the big screen again after her 'Battleship' debut - this time in Seth Rogen's 'The Apocalypse'. He said:

"I think she's gonna be in the new movie that I'm doing, Seth Rogen's directorial debut. I think she has a little part in that."

The singer is quoted by the Belfast Telegraph saying that she often feels that some people simply disregard her and don't realise that she has worked hard in the music industry for years. She said:

"People who haven't bought my album or seen me live, they think things like I don't write my own music or [don't know] I worked my way up since I was 13 to get into the music industry."

Lott is also quoted speaking about her forthcoming new album - something that is set for a "Motown and soul" feel. She said:

"I'm going to start putting some ideas together soon. I just want to go back into the Motown and soul vibe. I would like to make the album with that whole sound, because that's the music that I love."

Speaking to People, Beyoncé opened up on life as a new mother, admitting that previously she never thought there would be a day when she would go without heels - but that has all changed. She said:

"I never thought there would be a day when I wouldn't wear heels. Now that I have a child, I walk around holding her all day, I'm buying loafers and oxfords. I love them because they're comfortable, and shorter heels too."

Her husband Jay-Z meanwhile is seemingly a fan of the laid back approach. She added: "He likes me more natural - just more relaxed, natural me."
