Spectators at the 113 th annual French Open got an unexpected treat when two competitors engaged in a dance battle.

The epic dance-off between Frenchmen Gael Monfils and Laurent Lokoli went down Saturday on French Open Kids' Day at Roland Garros stadium in Paris.

DJs Bob Sinclair and Big Ali set the tone for the match-up by playing Lil John's "Turn Down for What," then each player took turns serving up his best pop and lock and robot dance moves. Based on the crowd's reaction, Monfils appeared to win the battle.

The tournament had its official kickoff Sunday.
