The buff star showed off his muscular form today as he enjoyed a spot of swimming while soaking up the sun in St Tropez with his girlfriend.
Kellan revealed his playful side as he pretended to act like Tarzan and drummed his fists against his chest in order to amuse his girlfriend.
In fact the star was practising for his latest role as he is currently filming a reboot of Tarzan, in which he plays the title character, with the movie due for release next year.
