Heroes actress Hayden Panettiere seems to have been having a whole bunch of fun at the Cannes Film Festival in France.

Apart from attending all the swanky parties and events, she has been pictured getting smothered in sun tan oil by her reported new beau, British TV celeb and serial celebrity dater Steve Jones.

And just this morning we caught up with Hayden having even more good times, jet-skiing around with a pal while their friends looked on.

We're not sure what Hayden's next TV show/movie project might be, but looking at these pictures she might find it hard getting back to real work any time soon.
