UFC bantamweight champion and part-time actress Ronda Rousey (Furious 7) is out and about promoting her new book "My Fight, Your Fight." Last night during a book signing at Barnes & Noble, Rousey showed off her silly side by dancing with Baby Groot.

This is based on the memorable scene from the closing credits of James Gunn's blockbuster film Guardians of the Galaxy. It has Baby Groot dancing to the Jackson Five’s “I Want You Back,” while stopping ever so often to avoid detection from Drax the Destroyer (Dave Bautista), who is busy cleaning his knife.



Watch Rousey get her groove on in the video clip below.

On August 1st, Ronda Rousey will defend her bantamweight title against Bethe Correia at UFC 190 in Rio de Janeiro.
