Fresh from their red carpet appearance at Venice Film Festival 2013, Diane and Josh hit the beach in LA to show off their surfing moves.

We were impressed to see Josh mastering the board like a pro, as the star is still recovering from a recent foot injury, but the ever-graceful Diane caught our eye looking super dainty, even in a wetsuit.
