Even Bill Belichick is a Swiftie.

The former NFL coach went to Taylor Swift’s Eras Tour in Amsterdam with the singer’s boyfriend, Travis Kelce, and Patrick Mahomes.

On a recent episode of the “Fore Play Podcast,” Barstool Sports’ Sam Riggs Bozoian discussed the trio’s journey to see Swift in the Netherlands last week.

“Coach Belichick had hit up Travis Kelce, he was over there,” Bozoian told the crowd. “So at one point, we’re just in this box at the Taylor Swift show and we’ve got myself … we had Bill Belichick, Patrick Mahomes and Travis Kelce are just in this box at this Taylor Swift show in Amsterdam.”

“We’re in this box at Taylor Swift’s show, and we’ve got myself…” “We had Bill Belichick, Patrick Mahomes, and Travis Kelce just in this box at this Taylor Swift concert in Amsterdam,” Barstool Sports anchor Sam Riggs Bozoian stated.

Bozoian then revealed how the former New England Patriots head coach, 72, interacted with the Kansas City Chiefs players.

“They had a great interaction with Belichick,” the quarterback stated. “When they got in, they were like, ‘Hey coach!’ and they were all dapping up. “Just a bunch of football players shooting the s—t.”

According to the blogger, the entire encounter was “f-king chaos” and “was really cool.” He also posted a photo of himself with friends and Kelce, 34, while attending the Eras Tour on X.

While Belichick, who is now dating 23-year-old Jordon Hudson, appeared to maintain a low profile at the July 5 gig, where the tight end and the millionaire pop singer packed on the PDA after her performance at Johan Cruijff Arena.

The couple, who went public last September, emerged from behind the stage holding hands. Kelce then gave Swift, 34, a nice kiss on the head.

The following night, Mahomes and his wife, Brittany, both 28, were seen swaying and embracing in the audience while Swift played her hit song “Lover.”

The mother of two wore a dazzling Prada pajama set while spending time with her friend Miranda Hogue.

Brittany was seen checking on an upset Kelce, who appeared to wipe away tears while Swift performed a unique mashup of songs dedicated to him.

Swift sang “Mary’s Song (Oh My My My)” from her 2006 self-titled debut album for the first time in nearly 16 years during the Netherlands concert.

In the song, she sings, “I’ll be 87, you’ll be 89,” which has taken on new meaning since she began dating the sportsman. (His jersey number is 87, and Swift was born in 1989.)

After the “Cruel Summer” singer finished her third and final gig in the Netherlands, Kelce encouraged the Swifties to get revved up as they fled the stage together.
