Nick on Mariah's HSN Appearance: 'My Wife was Off the Chain'

"Extra's" Terri Seymour caught up with "America's Got Talent" host Nick Cannon after the show Tuesday -- and he talked about his wife Mariah Carey's recent stint on the Home Shopping Network.

"My wife was off the chain," Cannon laughed. "She was running the Home Shopping Network!"

While Carey was on HSN selling her jewelry line, Cannon made a brief appearance. He explained, "Yeah, I just showed, said hello, kissed her, got on a plane and came here. That's love. Show up and do what the missus tells you."
