Ellen Page's acoustic version of Britney Spears [1]'s song "Lucky" is gorgeous on its own, and it's made all the more so thanks to an improvised dance by her friend. The actress took to Twitter to share a video of the pair's collaboration [2], writing, "I acoustically cover 'Lucky' by Britney Spears while Emma Portner improvises live." Page's beautiful voice and Spears's 2000 hit are a perfect match, and the cover definitely deserves a spot on your rainy-day playlist.
