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 picture of the NFL coach, 72, wearing her merch 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 picture of him wearing one of Swift's Era's Tour sweaters.

Belichick, the legendary New England Patriots coach, 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 cheering Kelce and the Chiefs against New Orleans Saints after a two-game absence.

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

The Chiefs are bidding to win a third straight Super Bowl this season - a feat Belichick did not manage to achieve in his era of dominance with the Patriots. 

Kansas City went on to beat the Saints 23-16 on the night, advancing to 5-0 for the season ahead of a bye week next weekend.

Belichick's relationship with Hudson sparked controversy when it became public knowledge over the summer due to the age difference.

The pair immediately hit it off after meeting on a flight three years ago, before exchanging details after landing and keeping in contact over the next few months while discussing Jordon's school work and cheerleading routines.

Sparks then began to fly when Bill split from longtime girlfriend Linda Holliday in 2023, and a year on the couple are now official after being spotted in public frequently in recent months.

While they kept their relationship under the radar in the beginning, Belichick and Hudson were seen together in Croatia and at Tom Brady's Patriots Hall of Fame induction ceremony on June 12.

During their first meeting on a flight to Florida, Belichick even signed his now-girlfriend's notebook, writing: 'Jordon, Thanks for giving me a course on logic! Safe travels!'

He then added his signature and jotted down abbreviations of all six of his championship seasons.
