UFC fighter twerks on her opponent after a win... one day after shaking and crying in brutal weigh in

Ailin Perez celebrated her first-round victory at UFC Paris by twerking on her opponent as she got up from the canvas.

During the fight night in the French capital, the Argentine took on UFC newcomer Daria Zheleznyakova of Russia.

With a minute and change left in the opening round, Perez secured an arm triangle, forcing her opponent to submit early.

Perez then quickly got up and began shaking her rear end on Zheleznyakova's face as she gathered herself. As Zheleznyakova walked away, Perez repositioned her twerking to keep rubbing the win on her opponent.

Perez's second submission win brought her record to 11-2, as she's won her last four fights. On the other hand, Zheleznyakova suffered her second-ever defeat in her sophomore effort in the UFC, moving her to 9-2.

Despite winning, Perez forfeited 20 percent of her purse after missing weight on Friday. She underwent a brutal weight cut to make 135 lbs for Saturday's event, and the effects were glaring when she took the scales.

She slowly walked toward the scale and struggled to lift her feet to the platform. Once settled, Perez exhaled, eyes low to the floor.

Unfortunately, despite the concerning weight cut, Perez weighed in at 136.5 lbs, half a pound over the limit.

Nonetheless, she used the last bit of energy to flex her biceps and point up as she accepted her weight miss.

Hours after the brutal encounter with the scale, Perez appeared in much better conditions at the ceremonial weigh-ins before scoring the victory and signature celebration on Saturday.
