Justin Bieber, Demi Lovato, Joe Jonas And More Attend The 2010 White House Correspondents' Dinner

The nation's capital got a hefty dose of Hollywood star power this weekend as some of our fave celebs hit the town for the 2010 White House Correspondents' Association Dinner. Now, we weren't expecting much from this meal, but boy were we wrong, because apparently, nothing brings celebs together like politics (who knew?!). Seriously, the night was full of unexpected pairings and fab outfits. Check out our recap to find out more!

Justin Bieber has made it pretty clear that he'd love to date Kim Kardashian, and he definitely got a few steps closer at the Corespondent's dinner. Justin, who no doubt made millions of teen girls swoon in his tux, and Kim, who wore an elegant strapless gown, finally met up on the red carpet and seemed to totally hit it off. In fact, the Biebs even tweeted a picture of the two, saying "Look it's my girlfriend," and Kim played along by responding she officially had Bieber Fever (welcome to the club!).

Of course, Justin and Kim weren't the only surprising pair this weekend. We also caught sight of "Eclipse" star Anna Kendrick, who looked fab in a pale purple, strapless Elie Saab gown, sharing a table with "Glee's" Matthew Morrison.

Much like Kim and Justin, Demi Lovato, who was joined by the Jonas Brothers, also spent plenty of her night at the White House dinner tweeting away all the best moments (including a photo of Demi meeting Rosario Dawson and one Joe Jonas patting an Obama wax figure on the shoulder ). Demi and Danielle Deleasa were certainly lucky to be sporting such dapper men on their arms!

We couldn't have been more excited to see Cynthia Nixon and Kristin Davis, aka two of our favorite "Sex and the City 2" girls last night! We liked Cynthia's strapless grey Calvin Klein dress, although we would have liked to see her lose the bracelet and rock some simple jewels. As for Kristin, we liked the embroidery on the top of her 1969 Pierre Balmain Haute Couture gown but thought the bottom was a little lackluster. Next time, we'd love to see both these ladies steal a little inspiration from the "Sex and the City 2" closet!

"Iron Man 2" star Scarlett Johansson also made it to this weekend's festivities, rocking a short light pink dress that we thought had a little too much going on in the front (but overall we liked it). Oh, and as for the dashing guy next to her? That's her twin brother (that's right, Scarlett's got a twin, who knew right?!).

Who was your favorite celebrity pair from this weekend's White House Corespondent's Dinner?
