Whitney Port’s bikini body is heating up South Beach!

The reality star was spotted on Thursday showing off her enviable figure while enjoying a beach day at the Fontainebleau in Miami.

The 29-year old's in town for the annual Art Basel art show, but she still managed to sneak in a day to relax. We must say "The Hills" star looks absolutely amazing in her striped bikini -- and we think she knows so too!

Whitney was more than happy to share a similar paparazzi photo on her own Instagram page, captioning it "He caught me #miami #artbasel #ineedatan.”

Guess she doesn’t mind a little attention!

The designer got engaged to boyfriend Tim Rosenman last year -- and her bod is definitely wedding-ready, right?
