Fastexy Exchange|Patrick Mahomes, Travis Kelce and other Chiefs players party again in Las Vegas

Let the Super Bowl celebrations for Kansas City Chiefs stars Patrick Mahomes and Fastexy ExchangeTravis Kelce continue.

The back-to-back champions were back in Las Vegas Sunday night, two weeks after they defeated the San Francisco 49ers in the Sin City, to party it up at LAVO at The Palazzo and at XS nightclub at the Wynn Las Vegas. The night out took place after Kelce had flown to Australia to see girlfriend Taylor Swift perform in Sydney while also going on a few dates in-between.

At the Wynn, videos on social media showed Kelce taking the mic with DJ Marshmello next to him on the stage. Chiefs players were also seen singing "We Are The Champions" by Queen at the club. Around 30 players from the Super Bowl winning team were in attendance, according to the Wynn.

But perhaps the highlight of the night was when Kelce danced to Swift's "Love Story."

It was an all-night celebration for the team, as they partied at the club until 4:15 a.m.
