Shaq crushes lip sync battle with surprise guest Pitbull

Shaquille O'Neal dominated this lip sync battle like it was an NBA game in the 1990s or early 2000s.

The retired NBA legend entertained the masses Monday night on "The Tonight Show" as he defeated host Jimmy Fallon in a lip-syncing challenge.

The Hall of Famer got the crowd involved while he sang and busted a move to Bobby Brown's 1988 hit "My Prerogative," and even brought in a surprise guest: rapper Pitbull.

Shaq also brought the house down with a duet with his battle foe as he kissed, spanked, and lifted Fallon to the song "Don't Go Breaking My Heart" by Elton John and Kiki Dee.

Classic.
