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.

They may not have their names in lights in Las Vegas yet, but Fighting Gravity returned to the 'America's Got Talent' (Wed., 9PM ET on NBC) to remind us why their act was so mesmerizing. They finished third in Season 5, and proved they've still got tricks up their sleeves.

Each time we see Fighting Gravity on 'America's Got Talent,' we try to imagine what they would come up with a full production team and a bigger budget. The possibilities are just endless.

In the spirit of past 'AGT' greats, Stevie Nicks announced that last season's winner, Michael Grimm, is set to open for her on tour. She then did what Stevie Nicks does, and brought the house down with two separate performances. In all the fun, it was easy to forget that eight acts were up for elimination.
