The actress flaunted her slim frame in a strapless black bikini top with bright green bikini bottoms while holding onto a glass of wine next to the Fringe alum.

Audrina Patridge
This former Hills star knows how to balance work and play. While filming her new show 1st Look in Hawaii, Audrina Patridge took advantage during her downtime and caught some waves on Dec. 22.

Debuting her downsize! The Hills alum showed off her bikini body on the beach in Los Angeles on Dec. 1 after she reduced from F to C cups. "I couldn't conceptualize the weight of them in my body," Montag exclusively told Us in the Nov. 18 issue. "They felt like bowling balls on my chest. I felt inappropriate. Guys would stare at me really creepily and felt they had the right to because I had such big boobs."
