Talk about the stealing the show!

Katy Perry flaunted some major cleavage in a sexy black dress at the handprint ceremony for her and designer pal Jeremy Scott in Hollywood yesterday, and we can totally see why the pop star is the Moschino head hauncho's muse!

The "I Kissed a Girl" songstress stars with her good friend in The Vladar Company's Jeremy Scott: The People's Designer, and he admits that the flick is basically all about the buxom brunette and their bond.

"Katy is the arc of the film. When you see it, you'll understand. There's these iconic moments that everyone knows — like her on the field for the Super Bowl and us at the Met Gala on the stairs. And me kissing her hand. But then you have us in the car and me nervous, and her making me laugh and putting me at ease," he explained to Us Weekly.

This look is so Angelina-esque!
