Serena Williams loves The Little Mermaid just as much as you do. Ahead of the US Open kicking off on August 31, the professional tennis player blew off some steam in a very interesting way. Serena, who will be going for her 22nd Grand Slam title, attended a US Open party hosted by Delta Airlines earlier this week, where she got up on stage and sang The Little Mermaid's "Under the Sea." Serena's amazing performance included spot-on impressions of Sebastian, adorable dance moves, and hair flips.
