Audrina Patridge has renewed her contract with Bongo and is showing off her rockin' bod to celebrate.

While most of the country is bundled up to survive this most brutal of winters, the reality star stripped down to a teeny string bikini for Bongo's sultry new campaign, our friends at PopEater report.

"I am thrilled for my second season as the Bongo girl! It has been a wonderful partnership, and I really love the product," said the former "Dancing With the Stars" contestant.

The national campaign will debut this March in magazines, stores and on bongo.com.
