Ailin Perez She may not have put her opponent into a rear naked choke during her UFC fight on Saturday, but she definitely got her own rear end working – by twerking in her opponent’s face after winning via submission.

The bantamweight fighter competed in the Octagon at UFC Paris Daria Zhelezniakova …and she quickly dominated her opponent – causing DZ to be eliminated in the first round.

Perez jumped up…and you have to watch as she swung her ass back and forth right in front of her red-faced opponent, still gasping for air.

Perez wasn’t done twerking either…she threw back again after the referee raised her arm in victory – while her team pretended to throw money at her.

Apparently, this is a kind of thing, by the way … the fighter managed something similar in June, when she defeated Joselyne Edwards from Decision in June – so that’s kind of Perez’s characteristic victory dance.

While she may look thrilled now… Ailin had a difficult time leading up to this fight – at the weigh-in earlier this week she lost weight and became visibly emotional before an official escorted her off the stage.
