Bella Thorne may have arrived to Joel Silver's annual Memorial Day bash in a floaty white dress, but it wasn't before long that the teen star stripped down to her bikini and flaunted her fine form on the beach in Malibu. Nice booty, Bella!

The redhead and a friend couldn't help but capture the moments on camera, taking selfies of their beach frolicking. For her romp around the exclusive beach, Bella looked beautiful in a striped bikini top and white bottoms, which highlighted her pert bottom!

We aren't exactly sure how the 17-year-old Blended actress got invited to the star-studded bash, which included a celebrity guest list that boasted Diane Kruger, Chris Martin and January Jones, but invited she was!

Clearly the teen made the most of it!
