Ailin Perez started twerking after she got an impressive submission victory over Darya Zheleznyakova at UFC Paris.

We're not quite sure how to describe Ailin Perez's weekend at UFC Paris, but it was eventful. The Argentine mixed martial artist became the subject of some concern Friday when she reported for weigh-ins clearly looking like she had just suffered a brutal weight cut.

Perez (11-2 MMA, 4-1 UFC) submitted Zheleznyakova (9-2 MMA, 1-1 UFC) with an arm-triangle choke at the 3:52 mark of Round 1. The women’s bantamweight bout was part of the UFC Fight Night 243 preliminary card at Accor Arena in Paris.

After dominating her opponent, Darya Zheleznyakova, with a first-round head-and-arm choke submission victory, Perez decided to do her patented twerking following the victory. This time, though, Perez moved her rear end directly on her opponent’s face in celebration.
