Sara Bareilles performed a holiday themed song she wrote in homage to ‘Jersey Shore’ at Room 5 in Los Angeles last month. “For those of you who haven’t seen it, it’s ridiculous,” Sara told the audience before performing the tune set to Rihanna’s ‘Umbrella’. “But it’s like a trainwreck and I can’t stop watching it. It’s like these people you’re like, ‘I can’t believe you exist, but you’re real! And they made a show about you!’” Watch the intro and performance below.
