Spotted: Justin Timberlake Makes Some Friends In London

Every day a multitude of stars wander through the halls of MTV News to talk about their latest projects and goof around with our intrepid correspondents. But sometimes we catch stars elsewhere, and that's why we put together Spotted!, a daily compendium of stars in the wild.

The Oscar-bait movie season is well underway, and the biggest hit (both critically and commercially) so far has been "The Social Network," the somewhat-made-up biopic about Facebook founder Mark Zuckerberg that stars Jesse Eisenberg and is directed by David Fincher. The movie is getting accolades from all sides for its writing, direction and performances, including the one delivered by pop star turned movie star Justin Timberlake. The former *NSYNC member plays Sean Parker, a vaguely fictionalized version of Napster founder Shawn Fanning who helps turn Zuckerberg's dorm room creation into a multi-billion dollar project. Timberlake's performance is fantastically dynamic, sharp and funny, and he deserves all the accolades flowing in his direction. He has really been pounding the pavement in support of the film, too, and Thursday (October 7) brought him to London to visit BBC Radio 1. Outside the studio, he signed autographs for and chatted with adoring fans who at this point probably know JT more for his movie roles, bits on late night talk shows and guest spots on "Saturday Night Live" than for his watershed 2006 album FutureSex/LoveSounds.

Timberlake wasn't the only star in the sunlight, as both "Jackass" founder Johnny Knoxville and late night host Stephen Colbert made their way to the set of "The Late Show With David Letterman." Click here for these photos as well as the entire "Spotted" archive, which features over 500 candid shots of stars like Britney Spears, Taylor Swift, Justin Bieber, Miley Cyrus, Lady Gaga, Eminem, Jay-Z, Katy Perry, Madonna, the Jonas Brothers and Rihanna!
