Kristen Stewart and Dakota Fanning both arrived at the time of their offscreen counterparts, Cherrie Curie and Joan Jett, at last night's premiere of The Runaways. Dakota went first in her stunning Valentino dress and Ferragamo shoes while Kristen surprised us by showing up in a hot pink Doo Ri dress paired with Jimmy Choos. Dakota says she's yet to check out the first Eclipse trailer though hears fans are already wanting more! Speaking of the Twilight saga - Taylor Lautner rounded out a week of being Kristen's date by attending the red-carpet screening after the Oscars. Taylor signed autographs for fans and was the last to head in and check out the movie. Unfortunately, Rob wasn't able to return the Remember Me favor and attend Kristen's premiere, but his movie is out today so check out Buzz's review.

Reese Witherspoon headed to Washington DC yesterday to make the rounds on behalf of Avon's philanthropic campaign. First up was a breakfast meeting, where Reese spoke about their anti-domestic violence efforts. She was then off to the White House to join First Lady Michelle Obama and Secretary of State Hillary Clinton at a ceremony to announce a donation from Avon to the Secretary's Fund. Reese skipped out on Sunday's Oscars ceremony in order to make her trip East, but she still stars in one of our favorite ever Academy Awards moments.

David Beckham joined AC Milan last night at Manchester's Old Trafford stadium in a rematch against the city's United soccer team. The two squads first faced off last month when the Brits won 3-2 - and this time around, David and his Italian team lost by an even bigger margin of 4-0. David didn't seem too upset by the outcome, but that may have been because the crowd at his former home field rose and greeted him with applause when he started to play.
