How’d Patrick Mahomes celebrate his new $503 MILLION contract?

PRIVATE JET WITH TRAVIS KELCE TO GOLF, BABY!!!!

360aproko Sports has obtained video of the Kansas Chiefs superstar QB touching down in Lake Tahoe on Wednesday … and the half-a-billion-dollar man is clearly wasting no time enjoying his new riches.

Mahomes and Kelce shared a PJ ride together … before the duo will hit a celeb tournament at the Edgewood Tahoe Golf Course this weekend for the famous American Century Championship.

Mahomes looked to be in good spirits after getting off the plane … he posed for some pics and then hopped onto a (fittingly) Coors Light-themed shuttle bus.

Of course, Pat’s got every reason to celebrate this week … the 24-year-old just signed the biggest contract in the history of sports — putting him in line to earn well over $40 million per year until 2031.

Yeah, something tells us if the private jet wasn’t already paid for … Patrick’s picking up the tab now.

Congrats!!
