Vulture premiered the lyric video for Keira Knightley's version of "Lost Stars" from the "Begin Again" soundtrack. In the film, Knightley stars as Greta, a fledgling singer-songwriter, dumped by Dave (Adam Levine) after he becomes a huge pop star. Mark Ruffalo's character hears Greta sing in a New York City bar and helps produce her first big album.
In a big-movie first for Knightley, she sings on multiple tracks on the film's soundtrack, which is out July 1 on Interscope Records. The soundtrack features two versions of "Lost Stars," one from Knightley and one from Levine. (You can hear Levine's acoustic version on YouTube.)
