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.

We love Hayden Panettiere, and a big part of our infatuation is due to that hot, sexy ... brain of hers! She knows it, too. Here our girl Hayden is sporting a shirt proclaiming "This Girl's a Genius" as she exits the hot Koi restaurant in L.A. with mother and manager Lesley Panettiere. Anything but coy, if you ask us!

Hayden Panettiere and Milo Ventimiglia are not dating, okay? They're just spotted together, a lot, and can't take their eyes off each other.

Then again, if the alternative is watching NHL action, perhaps that doesn't mean as much as we think it does. After all, what are they supposed to do? Count on the L.A. Kings game Saturday night to entertain them?

What would Milo Ventimiglia say about this?

Just when we were ready to christen Halo (Milo and Hayden Panettiere) the newest celebrity couple - regardless of whether the Heroes co-stars admit to getting freaky or not - along comes this picture of our girl with another popular TV star, and potentially forming another celebrity couple name.

They're talented, they're cute and they're 37 years old ... combined! After a day of cheering on the set of Heroes, Hayden Panettiere engages a fellow young starlet, Hilary Duff in conversation at Teen Vogue's Young Hollywood party Thursday.

In addition to Hayden and Hilary Duff, we're guessing Teen Vogue intern Lauren Conrad and her boss, Whitney Port, were on hand for the event. Although at 21, LC might consider herself a little old for the "young Hollywood" set.

Hayden Panettiere has been 18 for a whole month now. In that time, she's ditched boyfriend Stephen Colletti and, apparently, taken up with her co-star on Heroes, Milo Ventimiglia. We really think so now. Up until this point, such rumors were mere celebrity gossip - fun allegations based on circumstantial evidence.

That was then. This video - shot at a Duran Duran concert in downtown Los Angeles at an official after-party of the Emmy Awards - is now. Well, Sunday.
