Bring on the PDA parade!

Selena Gomez and Justin Bieber weren't shy about showing off their affection while vacationing in Maui, Hawaii, on Thursday. After exchanging several kisses on a jet-ski and holding hands on the beach, a bikini-clad Gomez, 18, jumped into her boyfriend's arms and straddled him on the beach.

Their fun in the sun continued when the "Wizards of Waverly Place" star and Bieber, 17, went parasailing later that afternoon. Still, Bieber -- who recently got an ace of spades tattoo on his left forearm -- didn't exactly feel like a daredevil during the excursion.

"1,200 feet in the air...not the best feeling," he tweeted.

The lovebirds flocked to the Aloha State on Monday, just one day after Bieber picked up several trophies at the Billboard Music Awards in Las Vegas.
