Playboy model and former Dancing with the Stars contestant Joanna Krupa celebrated her 32nd birthday in nothing but her bikini.

Hotness must run in the family as Joanna's smokin' sexy sister Marta joined her older sibling and her fiance Romain Zago in the sun and sand of South Beach, Miami. The model's fiance tweeted during the birthday weekend, jokingly calling his girl a "pain." He wrote:  

"My fiancee @joannakrupa can be such a pain in the a$ on Sundays... You just wouldn't understand... The things we do for love...lolololol Watch it mr zago!"

Joanna competed in season nine of Dancing with the Stars with partner Derek Hough. Hough has since taken a leave of absence from the ballroom, but DWTS is still in full swing as the competitors return to the dance floor Monday night to vie for the coveted mirror ball trophy.
