PARTY LIKE A CHAMP XS Nightclub Las Vegas
Merab Dvalishvili had himself quite the weekend ... he defeated Sean O'Malley for the UFC Bantamweight championship, and celebrated the win deep into the night at Sin City hotspot!
We're told the 33-year-old Georgian hit up XS Nightclub inside Wynn Las Vegas around 1:30 AM ... rolling up to the joint with around 70 people to celebrate the massive moment -- and of course was showing off his new hardware!
MD received a welcome worthy of a champ -- he was greeted with illuminated LED marquees, massive photos, and an LED drumline as confetti flew in the air.
