Rumors are continuing to skyrocket around Mariah Carey and Nick Cannon's reported split, and it looks like people close to the America's Got Talent host saw it coming.

Nick Cannon 'Handles The Pressure?'

On Tuesday, Radar Online reported that an on-set source from Wild N Out noticed that something was off between the couple, which didn't make it a shock when the divorce stories came along.

"Their separation wasn't a surprise. People knew it was coming. It was just a matter of time," the source said.

Nick Cannon & Mariah Carey Were 'Fighting A Lot?'

There was apparently a time when Carey would visit her husband on set, but after a while she focused on herself, according to the insider.

"During the first season Mariah made an appearance. But this season she didn't come to the set at all," the source said. "She was working on her own stuff and Nick just did his stuff."

It looks like music was the singer's primary factor along with the couple's twins Morocaan and Monroe. Unfortunately for her husband, it seems like he wasn't an important part of her life anymore.

"Mariah always wanted to be with her kids," the source said. "She didn't seem to care about Nick and more focused on her music."

According to British magazine Closer as published by The Malay Mail Online, Carey might find Cannon to be immature and doesn't want to tolerate that.

"She's described Nick as a 'man-child' and says she can't deal with his immaturity- she feels like they don't have anything in common anymore and that he still wants to lead the life of a carefree bachelor, while she prefers nights in with the kids," a source said.
