Hayden Panettiere looked the cat's whiskers as she paraded around on the beach in a Hello Kitty bikini. The 20-year-old happily flaunted her tanned and toned figure in the two-piece during a recent visit to Malibu beach. Perhaps the actress, who recently had her long blonde tresses cut into a stylish crop, has been taking fitness tips from her boxer boyfriend, Wladimir Klitschko.

She has been dating the 34-year-old Ukrainian since late last year. 'I've never had an athlete as a boyfriend before, and it's an exciting experience,’ she said recently. Heroes, the TV show which made Panettiere famous, was axed in March by the U.S. NBC network after a dramatic loss in viewers. But creator Tim Kring is keen to bring the drama back for a mini-series in order to wrap up loose ends. Meanwhile, the young actress has joined the cast of horror flick Scream 4, where she will star alongside Courteney Cox and Emma Roberts.
