Mariah Carey was all over husband Nick Cannon after performing her new song Obsession on America's Got Talent.

Nick, who hosts the show, had been very professional as he introduced Mariah, calling her "a very, very special someone", and the "amazing Mariah Carey."

But as the pair shared the stage afterwards, the singer showed that the honeymoon period is far from over by manhandling her man in front of millions of viewers.

As Mariah draped herself over her husband, Nick called her his "soul mate".

And as they walked offstage, Mariah couldn't resist giving Nick's behind a little squeeze. Cheeky!
