Kristen Bell may be a newbie on Heroes, but she and a certain indestructible cheerleader are old pals.

“I’ve known Hayden Panettiere since she was 8 and I’ve watched her blossom into one of the loveliest young women out there,” she tells OK! at the Sprint Nextel and Tiffany & Co. event. “She is so articulate, so kind and so caring and I’m just proud of her. It’s like a very sisterly relationship. I adore her.”

The 27-year-old describes their friendship as “sisterly,” but you won’t catch them out and about every night. Instead, the buds prefer a girls’ night in despite what Hayden’s newly legal age may suggest.

“I don’t know about ‘go out and party'” says Kristen “She’s only 18!”

One relationship Kristen remains mum on, though, is her rumored romance with Kate Hudson‘s ex, Dax Shepard. Although recently spotted out and about together, the actress opted not to address the reports.
