How we love to see Today's feisty fashionista, Steven Cojocaru, doing teen makeovers on American Idol. Those kids need the help! "Who's the biggest challenge? All the guys," Cojo tells TV Guide Online. "The girls understood image and packaging — they were all over Mr. Fashion Guy like a cheap suit! None of the guys gave me lip, but I had to win them over."

Is Julia D'Amato as, er, difficult as she seems? "Julia was not a diva," he says, "but she knows herself. Some would say that's a diva ingredient. I liked that she came wearing killer high heels, which is totally cool in my book. I liked her whole attitude. I put her in Capri pants, and I wanted her to go a smaller size — she looked at me very J.Lo and said, 'These are fine.' She's no pushover."

Cojo's not as nice to everyone in his dishy new memoir, Red Carpet Diaries: Confessions of a Glamour Boy. But he's not too nasty. "If their stomachs get a little upset for an hour, that's fine," he laughs, "but I don't want to ruin anybody's day. I am not the Salman Rushie of fashion."

That's why some juicy gossip was excised from his final draft. "There were a couple of plastic surgery jokes about a star with lips that were one size, and then she transformed and sized up," he teases. "I felt that wasn't necessary." Drat!
