Michael Phelps Loses His Shirt While Partying with Diplo in Vegas

Michael Phelps was swimming in EDM this weekend — and even though he wasn’t in the water … the dude found a reason to lose his shirt anyway.

The all-time Olympian — who’s got 23 gold medals to his name — was on hand Saturday night at the XS Nightclub within the Wynn Las Vegas resort … and he was in partying mood, which was only facilitated further with Diplo in the DJ booth and a packed crowd.

Mike and Diplo bro’d out behind the turntables … and it looks like MP got so hyped, he ended up going bare-chested amid al the festivities. Maybe he was celebrating a bet on Gervonta Davis — who won a big boxing match against Ryan Garcia earlier in the night.

Speaking of fighters … Mr. Conor McGregor was also in attendance, and Phelps got in a battle pose with the guy. He also smiled for the camera alongside Travis Kelce!

There was even more star power in the crowd … Sabrina Carpenter, Dixie Damelio and Loren Gray — not to mention Michael B. Jordan, Chace Crawford, David Dobrik and others.

Of course, there were even more A-listers who were front and center for the fight itself … these are just a handful of celebs who decided to rage after the fact at this particular club.
