Masked Jason Kelce took over Super Bowl DJ set while Travis and Taylor Swift shared romantic moment

Jason Kelce was the real winner of Super Bowl LVIII.

The former Philadelphia Eagles center got to let his hair down in Las Vegas last year after younger brother Travis beat the San Francisco 49ers 25-22 to lift his third Lombardi Trophy.

The Chiefs tight end evoked the Beastie Boys classic: "You got to fight, for your right, to party!" after the game and Jason took that advice to heart.

The elder Kelce sibling rolled up to a Sin City club in a Big Yeti T-shirt and checkered Chiefs dungarees to steal the show at the 2024 Super Bowl after-party.

Video footage emerged of Jason, wearing a Mexican wrestler's mask, taking over a DJ booth and joining EDM artist Marshmello to ramp up the crowd at Zouk Nightclub.

In another viral video, the Eagles star was spotted dancing wildly behind the decks and clapping his hands while Travis and girlfriend Taylor Swift enjoyed a more intimate moment.

The couple danced together and shared a kiss while the pop star's 'Love Story' played in the background -- and it was quite the contrast to what Jason was doing at that specific moment.

"The duality of man," one prominent account on X posted as footage showed the Kelce bros enjoying very different nights out.

"Jason is a damn national treasure," said another.

"Jason is my spirit animal," added a third.

"The contrast is hysterical," wrote a fourth.

"Jason is a whole vibe,"; commented another fan.

Jason was a little worse for wear later in the night as footage showed him stumbling out of the after-party and heading back to his hotel after the celebrations were over.

Earlier in the day, Jason joined Taylor Swift and her A-list friends including Ice Spice and Blake Lively to watch Super Bowl LVIII at Allegiant Stadium.

They watched the game from a private suite and footage of them meeting before Travis took to the field went viral.

Swift managed to make the big game after catching a late flight back from a gig in Tokyo, Japan.

The long-haul trip was well worth it as she got to see Travis win his third Super Bowl ring.

The KC TE had nine receptions for 93 yards and zero touchdowns in a nail-biting game that saw the Chiefs win in overtime.

The couple eventually found each other amongst the camera and confetti and shared a kiss to seal the victory.

Speaking after the Chiefs' victory, Kelce was asked whether anyone has had a better week than he and Swift after her latest Grammy success.

To which he said: "On top of the world right now, baby. It's a good feeling."

However, there will be no Super Bowl celebration this year after Travis' Chiefs were humiliated in Super Bowl LIX.

The three-peat chasing Chiefs were humbled by the Philadelphia Eagles at the Ceasars Superdrome in New Orleans, finding themselves on the receiving end of a 40-22 blowout.

Travis addressed the agonizing defeat in the latest episode of his award-winning New Heights podcast, released Wednesday.

"It just wasn't our day," he told Jason.

The 35-year-old also shed light on his NFL future, with speculation rife that he will now retire this offseason.
