Travis Kelce attends girlfriend Taylor Swift's London concert

Travis Kelce, 34, was seen at Taylor Swift's London Eras Tour kickoff at Wembley Stadium, marking his first public appearance with the pop star since last month.

An enthusiastic fan captured the NFL star signing her "New Heights" hat from the VIP tent, where he was accompanied by friends, just before the concert commenced.

Accompanying Kelce were his brother and sister-in-law, Jason and Kylie, experiencing their first show of the world tour.

Travis' friend, Ross, who bears a resemblance to him, also traveled across the pond to witness Swift's performance.

Other notable attendees included "Bridgerton" star Nicola Coughlan, "Queer Eye" personality Jonathan van Ness, and model Cara Delevingne.

The retired Eagles center was observed sporting numerous friendship bracelets on his arm as he amiably exchanged them with enthusiastic Swifties in the crowd.

Earlier in the day, fans caught wind that Jason, aged 36, might be attending the event when he was seen taking pictures with fans at a London pub, having recently returned from a brief trip to the South of France for the Cannes Lions Festival.

Accompanied by his brother and sister-in-law, the Kansas City Chiefs star, who had joined Jason at Cannes Lions for their "New Heights" podcast recording, arrived at the venue slightly after them but still managed to make it before the 34-year-old pop star took the stage.
