Magician Seth Grabel knows what America likes. Kids are adorable, and he incorporated them into his act in a fun way on 'America's Got Talent' (Tue., 9PM ET on NBC). With a 'Back to the Future' theme, Grabel made a DeLorean appear on the stage, claiming it was from the past.

To prove it, he opened it to reveal three adorable youngsters dressed up like Piers Morgan, Sharon Osbourne and Howie Mandel. But the best moment of the act came when Piers asked the Li'l Sharon Osbourne what her name was.

"Hello darling," Li'l Sharon replied, to tremendous applause and a standing ovation from Mrs. Osbourne herself.

It's not just the amateur and semi-pro acts that appear on 'America's Got Talent' that fear they'll receive a dreaded, ear-piercing strike from trigger-happy judge Piers Morgan.

Musical guest Stevie Nicks confided to AOL TV that she, too, thought Morgan might give her a red X when she was performing on last night's results show.

Nicks was there to promote her upcoming tour (last year's 'AGT' winner Michael Grimm will open for her) and she sang two songs including one from her latest album 'In Your Dreams.'

Morgan not only didn't not buzz Nicks, he even gave her a standing ovation.
