Jason appeared to hit the jackpot in Las Vegas after heading to the casino with wife Kylie the night before Super Bowl LVIII.
Jason, who is still weighing up his future in the NFL, is in Sin City with Kylie this weekend to cheer on brother Travis and the Kansas City Chiefs against the San Francisco 49ers at Allegiant Stadium.
The Philadelphia Eagles veteran has certainly been enjoying himself on Super Bowl week as he lets his hair down in the offseason, attending Adele and U2 concerts, playing blackjack and recording a special episode of his and Travis’ New Heights podcast.
And on the eve of his brother’s fourth Super Bowl appearance, Jason was seen celebrating a big casino win alongside Kylie and friends at The Cosmopolitan hotel.
In footage captured by Dailymail.com, the 36-year-old lets out a huge cheer after his gambling success and throws his arms out in celebration.
Kylie could also be seen cheering and laughing after her husband’s victory at the casino.
Earlier in the day, Kelce enjoyed a hilarious interaction with Adele after attending the singer’s concert in Vegas.
Adele is in the middle of doing a Vegas residency at Caesars Palace on the Strip and Jason went to one of her shows alongside his wife Kylie.
At one point, the British songstress took a poll of the crowd to see if they were there to support the Chiefs or the 49ers.
Video then captured one person, supposedly Kelce, shouting out ‘EAGLES!’ which generated a reaction from Adele.
What did you say?,’ she asked before commenting, ‘You sound drunk and like a football fan.’
Later in the evening, Kelce was seen beside Kylie singing along as the UK singer went through a rendition of ‘Someone Like You’.
Jason and Kylie will be at Allegiant Stadium to support Travis in his bid to claim a third Super Bowl ring on Sunday night.
