Heidi Montag is a Baywatch Bikini Babe

Plastic surgery princess Heidi Montag flaunts her fit figure as she frolicks along the beach in Los Angeles on Thursday.

The Hills star channeled her inner Baywatch babe as she bounced across the sand in a skimpy pink bikini.

Heidi, 21, played pretend lifeguard as she toted a red life preserver and got a birdseye view of the beach from the lookout tower.

On Wednesday, Heidi and manager boyfriend Spencer Pratt celebrated her Us Weekly cover girl status at the Us Hot Hollywood Party. She admitted to having rhinoplasty and breast augmentation.
