Nick Cannon Without Wedding Ring on 'America's Got Talent'

Nick Cannon hosted America’s Got Talent's semi-final show Tuesday night and he didn’t wear his wedding ring.

Not wearing his ring seems to confirm that sadly, it's all over between him and Mariah Carey. He was still wearing his band of gold on the show just last week, but that wasn't the case Tuesday night.

Carey is living in a New York apartment while Cannon has been moving from hotel to hotel.

The reason for the split? People magazine quotes a source saying that it's because her career is faltering while his is on the rise with America’s Got Talent.

"When things don't go well career-wise, sometimes you turn on your other half," the source said.

Now, that missing ring seems to say it all.
