Travis Kelce reveals what Patrick Mahomes was really doing at his Kelce Car Jam

Patrick Mahomes and wife Brittany were among the stars who descended on Kansas City for teammate and close friend Travis Kelce's charity event Saturday - but the quarterback's attention was seemingly elsewhere. 

The Chiefs star showed his support for his teammate's Kelce Car Jam and celebrated his 35th birthday over the weekend. 

But Mahomes had another cause to root for during the charity event Saturday evening. 

The Kansas City Royals kicked off their ALDS series against the New York Yankees as playoff baseball returned to the Bronx. 

And Kelce revealed that Mahomes, a big fan of the Royals, was anxiously watching their fellow Kansas City sports team during the charity event. 

'We've got Pat Mahomes back there somewhere,' Kelce said from the stage. 'He's glued to his Royals right now.'

While Kelce's event was a success, the same couldn't be said for the Royals. In a tight, dramatic thriller in New York, Kansas City slipped to a 6-5 defeat in the opening game of the series. 

Game 2 will be played in the Bronx on Monday night when Bobby Witt Jr. and co. will hope to tie the series before heading back to Kansas City. 

Meanwhile, proceeds from the charity block party are going to Kelce’s 87 & Running Foundation which raises funds for children in Kansas City and Cleveland. 

Patrick and Brittany were there to show their support at the second annual Kelce Car Jam, a showcase of swish cars belonging to the Chiefs star and his friends.

The Chiefs quarterback is close friends with his tight end, while Brittany has formed a tight bond with Kelce's girlfriend Taylor Swift over the past year.

The couple were greeted by dozens of fans as they arrived at the charity event in Kansas City.

Kelce and Mahomes will return to the field on Monday, when the Chiefs take on the New Orleans Saints at Arrowhead Stadium.

It will be the first time Jason Kelce has called a game involving his younger brother since the former Eagles center joined ESPN as an NFL analyst.

Jason and his parents, Donna and Ed Kelce, arrived at the charity event shortly before Mahomes. Kansas City defensive end George Karlaftis was also spotted at Kelce Car Jam. 

Patrick and Brittany Mahomes arrived in a black Ferrari but Kelce planned to show off the 1970 Chevrolet Chevelle that he famously drove Swift around Kansas City in last year.

'This year is the second year we've done a car show, basically a block-party style event, that will showcase some of the city's top automobiles from the Fuel House, a fun car club out here,' Kelce said.

'And then I guess a bunch of others that are lined up. It's gonna be fun. I should have my old school '70 Chevelle all revved up and ready to rock and roll. If not, I'll bring one of the other cars that I have.'

Kelce and Swift have been on several double dates, including at last month's US Open final, when the two couples watched Jannik Sinner beat Taylor Fritz in the men's final at Flushing Meadows.
