Adam Levine is starring in this week's new release Begin Again [1] as a musician who hits it big, and while the role isn't that much of a stretch, we're psyched because, of course, it means that Levine (who made the POPSUGAR 100 [2]) is performing in the movie. We have the video for "Lost Stars," a gorgeous song created for the soundtrack of Begin Again, which also features a ton of footage from the film, so you get to see Levine being soulful and sexy, along with costars Keira Knightley [3] and Mark Ruffalo [4], who also star in the movie. The new song is available on iTunes today, and the soundtrack for the film [5] comes out Tuesday, July 1. Enjoy!
