Mariah Bars Nick From Talking!

Just a day after his surprisingly candid admission that he and Mariah Carey's marriage is indeed strained comes news that he's largely been silenced by his wife.

Following reports that the couple's six-year marriage had hit a rocky patch, Nick Cannon, 33, confirmed in an interview that there was trouble in paradise.

But according to TMZ, the pair's lawyers struck up a confidentiality agreement, which bars him from sharing details of their divorce - or face 'severe financial penalties'.

Sources tell the website that while America's Got Talent host Nick has been muzzled, his estranged wife has retained rights to announce the split on their own terms.

And, as was seen in his recent interview with US TV show The Insider, Nick towed the line, only confirming that they were living separately, as he refused to discuss other details.

He told The Insider: 'There is trouble in paradise… we have been living in separate houses for a few months.'

After shooting down rumours that cheating caused the break, the star said his three-year-old twins - son Moroccan and daughter Monroe - are his 'main focus'.

On the same day his interview was released, Nick posted a video to his Twitter account, where he accepted the ALS Ice Bucket Challenge in nothing but a towel.

He had promised to enact the charitable dare naked, but compromised with the wrap around his waist.
