That's quite an eyeful! Katy Perry's ample assets were on full display on Tuesday, Sept. 8, as the Teenage Dream star joined designer pal Jeremy Scott for a Hollywood Boulevard handprint ceremony at the premiere of their new movie.

Wearing a very low-cut black dress (with an equally high thigh slash), Perry displayed her stunning curves (and narrowly avoided a wardrobe mishap!) as she bent forward on all fours to plunge her hands into the wet concrete slab outside the TCL Chinese Theatre.

The handprint ceremony was part of the Los Angeles premiere for her and Scott's new film The Vladar Company's Jeremy Scott: The People's Designer, which features the "I Kissed a Girl" singer as one of Scott's main muses.

"Katy is the arc of the film," Scott told Us Weekly before the duo got down on their knees to plant their hands in concrete. "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 added.

As for their outfits (which showed off not only Perry's cleavage but also her designer pal's full chest), "We're matching!" Perry told Us, laughing. "We're twinning. I think that's the word on the streets these days, and Jeremy's just always is so kind to let me borrow things. I turn into a pumpkin at midnight though," she joked.
