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.
