Movie Celebrity Gossip – Kristen Bell, the Heroes star, 28, is going through a second childhood — and it’s all thanks to her role in new kids’ movie Astro Boy. Kristen voices a character in the Manga-inspired animated movie and has ended up taking a lot of her work home with her.

“I didn’t know Astro Boy at all before working on this movie, but now I’m immersed and have all the little toys and stuff,” says Kirsten. “I just love the characters. They are so cute. The toys are great to play with — even if I am maybe a little too old. I guess I’m just a big kid!”

Bell’s Heroes costar Hayden Panettiere recently revealed that the cast of the hit TV show are like family.

“We really are the closest cast,” she said. “We’re just like brothers and sisters that just sit there and poke each other’s buttons.

“We’re the ones who have to be there to take their egos and shove them on the ground and stomp on them. They do it to mine all the time. I’m the butt of everyone’s joke.

“I’m the little sister who gets it more often than not. There are combination of them that get together and it’s just ‘No, leave me alone. I’m tired of being made fun of’.”
