George Russell Celebrates Vegas G.P. Win W/ Swedish House Mafia At XS Nightclub

F1 star George Russell partied like a champion Saturday night … hitting the strip and hanging with the Swedish House Mafia after winning the Las Vegas Grand Prix!!

The Mercedes driver held off the competition after starting in pole position … finishing the 50-lap race more than seven seconds ahead of second-place finisher and teammate Lewis Hamilton.

The 26-year-old was in the mood to commemorate the victory with some good tunes … so he hit up the Sports Illustrated Circuit Series Party at XS Nightclub inside the Wynn Las Vegas after the victory … bringing his girlfriend, Carmen Montero Mundt, along for the festivities.

It looked like a fun-ass time … and Russell will be able to enjoy the third win of his career for a bit before returning to the track for the Qatar G.P. next weekend.

Overall, it was yet another star-studded event for Formula One … with names like Sylvester Stallone, Paris Hilton, LISA and Noah Lyles attending the weekend in Sin City.
