Russell Brand may want to look away right now as his soon to be missus has been snapped cavorting on a beach with a young, hunky actor.

But Brand can still hold onto his top hat and tux as Katy is merely acting for her new video, Teenage Dreams.

Ex OC star Josh Kloss plays Katy’s love interest in the new video, where the pair are snapped in a number of sensual poses including Katy straddling the actor as they dance together on the beach.

Let’s hope Russell is the understanding type..
