PDA of the Day: Vanessa Hudgens and Austin Butler's Steamy Ocean Kiss

Starlet is spotted smooching her main squeeze while vacationing in Hawaii

Vanessa Hudgens is proving that distance definitely makes the heart grow fonder.

Back in the U.S. after an awkward promotional blitz in Australia on behalf of her new flick, Journey 2: The Mysterious Island, the 23-year-old starlet certainly wasn't shy about showing 20-year-old boyfriend Austin Butler how much she missed him as the two packed on the PDA in Maui on Thursday.

Of course, locking lips for all the world to see is nothing new for these two. Ever since they began dating in September, the cute couple can't seem to keep their hands off each other, whether it be snuggling over shakes or getting passionate by a pool.

Ah, young love.
