A Pair of Heroes: Hayden Panettiere & Kristen Bell

With roles on two hot television shows this fall, Kristen Bell is giving Lauren Conrad a run for her adorable, blonde money. Plus, she can actually act!

Below, Kristen Bell joins her Heroes co-star, Hayden Panettiere - quite the pair of cuties, we'd say - at a Christian Louboutin cocktail party hosted by Saks Fifth Avenue & Style.com at Hollywood's S Bar on Wednesday.

Bell, the former star of Veronica Mars, has signed on for a 13-episode story arc on Heroes, and is reportedly being considered as a full-time cast member after that.

She also serves as the mysterious narrator on The CW's Gossip Girl - Kristen Bell voices the mysterious girl who blogs high school gossip. It's actually a pretty good show, for those of you who haven't checked it out.

As for Bell's counterpart in the picture above, she's everywhere these days - and the 18-year-old starlet with beauty and brains is quite the fashion connoisseur.

"These were my birthday gift," Hayden Panettiere said of the black peep-toe shoes she wore in honor of designer Christian Louboutin. "I'm addicted!"
