We're not sure why Hayden Panettiere is in Cannes, but as long as she's prancing around on a private yacht in a bikini, there's no complaints here! The Heroes starlet was snapped sunning (and sunscreening) herself earlier today, and we have to admit, she's looking smokin' hot! And is it just us, or has she slimmed down a bit too?

Think Milo is kicking himself after looking at these shots? Actually, Hayden probably doesn't care what he thinks, because she's found a new man! The 19-year-old actress was spotted hanging out with sexy Welsh TV host/model Steve Jones, and the two looked very comfortable together. Hey, nothing says "I'm over you" like rebounding with another hunky 30-something man!
