Kellan Lutz Sharni Vinson  Spread Pictures

Could there be a sexier couple of tourists Saint Tropez?

Kellan Lutz and his very tan Aussie girlfriend, Sharni Vinson, looked happy and in love as they strolled hand-in-hand through the gorgeous French city on Monday afternoon.

The couple were more than happy to oblige a few fans who asked to take a picture with the Twilight star, and Sharni is such a doting girlfriend, she didn't mind snapping pix as multiple ladies posed with her man!

The finial installment of Twilight will premiere this November, but Kellan has already moved on to bigger and better things; he'll be playing the title role in Tarzan 3D, which hits theaters in 2013. We can't wait to see Lutz's muscles in 3D!
