Katy Perry and Victoria's Secret promise a ta-da moment

But Katy Perry's outfits for "The Victoria Secret Fashion Show" will be fabulous, says designer Todd Thomas.

"She has been a great partner for the show, and for us, as collection-makers, she has been just a dream," Thomas tells Zap2it. "I have gone to her and her stylist, Johnny Wujek. Their ideas are insane."

That, of course, is insane in the best way. Perry, on her honeymoon with Russell Brand, insists on pushing the fashion envelope and having fun.
