Jimmy Fallon is doing his shows in Orlando this week and faced off against Shaquille O' Neal in a LipSync battle that had Jimmy covering House of Pain's 'Jump Around' and Ariana Grande/John Legend's version of 'Beauty and the Beast' while Shaq covered Bobby Brown's 'My Prerogative' with a special appearance from Pitbull. Jimmy and Shaq ended with a special 'Don't Go Breaking My Heart' duet.
