Patrick Schwarzenegger Goes Shirtless in St. Tropez, Pours on the PDA with Girlfriend

Son of Arnold Schwarzenegger and Maria Shriver flaunts his washboard abs while on vacation

Another week, another chance to see Patrick Schwarzenegger's chiseled physique.

The son of Arnold Schwarzenegger and Maria Shriver, once again, showed off his buff bod on Thursday, this time in St. Tropez.

Sporting a blue bathing suit and nothing else, Patrick was spotted hanging out on a yacht with girlfriend Taylor Burns and siblings Katherine and Christopher as well as a few friends.

But Patrick obviously didn't let all the added company get in the way of a little PDA.

Embracing his gal on the deck at one point, the 19-year-old managed to steal a few smooches.

Ah, young love.
