Taylor Swift screams 'f***' as boyfriend Travis Kelce goes down in the endzone with furious pop star visibly frustrated during Chiefs' game against New England Patriots

Taylor Swift was visibly peeved on Sunday when boyfriend Travis Kelce went tumbling in the endzone and appealed for a penalty in the second half of the Chiefs' game against the Patriots.

Patrick Mahomes looked for Kelce in the back of the endzone early into the third quarter, with the score 14-10 to Kansas City, but amid pressure from a Patriots defender he fell to the ground instead of catching the pass. Moments before, Kelce saw the ball fall through his hands when trying to take another pass from Mahomes.

And as he called for a penalty, his girlfriend Swift was just as frustrated as he was, as she could be seen screaming 'f***' from her box seat on the FOX broadcast.

The pop megastar also appeared to say 'I wanna see [the play] back' after the drop moments before.

Kelce, who was also hit hard by the Patriots' Kyle Dugger after the drop, failed to earn a penalty as Myles Bryant's attempt to stop him from taking the catch was deemed legal just like Dugger's.

The drive ended in a field goal for the Chiefs, who wound up winning the game 27-17.

Kelce finished the game with just five catches for 28 yards.

Swift, who travelled to New England to watch Kelce for a seventh time this season, was caught sticking her tongue out as she made an appearance on the big screen to a mix of cheers and boos.

Sitting in one of Gillette Stadium's suites, she was spotted chatting with the wife of quarterback Patrick Mahomes , Brittany.

Swift's dad, Scott, also made the trip up to the Boston area.

The singer was also joined by close friends Alana Haim, who is a member pop rock band Haim with her two sisters, and stylist Ashley Avignone.

Swift was named the biggest celebrity CO2 polluter of the year in 2022.

As her romance with Kelce has developed, she has only flown back and forth between New York and Kansas City, but has also made trips in-between performances in South America for her ongoing Eras World Tour.
