What fun is spending time in the sun if you don't have a few close friends in tow? Stephanie Pratt soaked up some major rays during her Hawaiian pre-birthday getaway on Wednesday, April 10, with two adorable bulldogs on leashes, happily trotting through the waves.

The chubby pups looked content as they frolicked in the waves and ran circles around Pratt, who turns 27 on Thursday, April 11. The former Hills star looked on in bemusement as she watched them enjoy the sand and surf.

Pratt, who wore a two-toned blue bikini, looked tan and fit herself as she later grabbed a blue football to toss around with friends in the clear island water. The reality star previously told Us Weekly that she's spending some down time with close friends as part of an epic pre-birthday getaway.

"I work out five days a week," she told Us of her impressive physique. "Everything from boot camp to a hike to playing soccer."

And the vacation has been a long-time coming, Pratt revealed in a tweet on March 27: "Downloaded a bunch of surf movies for my flight right now — getting pumped up for my surf and sun tropical vacay. Bikini time. Stoked."

Pratt is the younger sister of fellow reality star Spencer Pratt, 29. The siblings were previously estranged after Pratt and wife Heidi Montag reportedly "decided they don't want me in their life," she told Fancast back in 2010.

The duo have since reconciled, however, tweeting at each other last summer on Spencer's birthday.

"Happy birthday @spencerpratt!" she wrote last August. "Hope you and @heidimontag are having a great time celebrating!"
