Bill Belichick, 72, mocks Taylor Swift at the Chiefs game – despite wearing her merch with his 23-year-old girlfriend

Bill Belichick mocked Taylor Swift in an appearance on ManningCast on Monday night — a day after a photo of the NFL coach, 72, wearing her merchandise was shared by his 23-year-old girlfriend.

Belichick grimaced in response to cameras showing Swift celebrating a play by her boyfriend Travis Kelce by saying, “Oh. Big first half for Kelce. Too big. Too big.’

It comes just a day after Belichick’s young girlfriend Jordan Hudson, 23, shared a photo of himself wearing one of Swift’s Era’s Tour jerseys.

Belichick, the legendary coach of the New England Patriots, has won a record eight Super Bowls: six as Patriots coach and two as defensive coordinator with the New York Giants.

He left the Patriots earlier this year after 24 seasons and is currently working as an analyst, despite being linked with an immediate return to coaching.

Swift, meanwhile, was back to cheer on Kelce and the Chiefs against the New Orleans Saints after a two-game absence.

She missed the two road games against the Atlanta Falcons and Los Angeles Chargers before returning to Arrowhead Stadium for the Saints game on Monday night.

The Chiefs are trying to win a third straight Super Bowl this season — a feat Belichick has failed to accomplish in his era of dominance with the Patriots.
