You never know what to expect from Lady Gaga." That was James Durbin -- tonight's opener and closer on "American Idol" top 4 performance night -- admitting that he was a little bit anxious before meeting the round two mentor, the Mother Monster herself.

She rocked outrageous makeup and lucite heels, forcibly swiveled James' hips, Elvis Presley style, and encouraged the remaining "Idol" hopefuls to get in touch with their naughty/silly/campy streaks.
