Here's the super hot super Heroes actress Hayden Panettiere, 20, showing off her special powers to thrill in a red Hello Kitty bikini. Hayden, who stars as self-healing cheerleader Claire in the hit TV drama, ditched the pom poms to show off her tum tum as she relaxed on a Malibu beach. The pint-sized scorcher has also been offered a role in the forthcoming horror film Scream 4.

But judging from these pics, Hayden's already having a wail of a time in shades and a baseball cap. An onlooker said: "Hayden looked in such great shape. "The other girls on the beach were envious of how at ease she was in such a skimpy bikini."That must be because she's a size Hero!
