Audrina Patridge is a Bikini Babe

The Hills star Audrina Patridge shoots her first movie role in a green bikini in Hawaii on Thursday.

The 23-year-old reality TV star shot scenes for the direct-to-DVD film The Reef, the sequel to Into the Blue (Jessica Alba, Paul Walker). Audrina plays a beach beauty whose boyfriend spoils her rotten.

Pal Lauren Conrad has said of Audrina’s new movie role: “I’m so proud of her! She moved to L.A. to become an actress and it’s so exciting to see it really happening to her.”

Shirtless costar Chris Carmack was spotted filming scenes for The Reef on Tuesday.
