The Kansas City Chiefs Super Bowl winner was filmed by fans taking his seat with a flamboyant white shirt with a green and gold pattern across it. In a separate video that emerged, Kelce was wearing his sunglasses while watching his girlfriend perform.

The 34-year-old Kelce flew to Singapore this week after his older brother Jason emotionally announced his retirement from the NFL after 13 seasons with the Philadelphia Eagles.

Saturday’s show is Swift’s last at Singapore’s National Stadium before a break for two months ahead of a lengthy run of European dates.

Kelce will likely follow her to Europe for some of her shows – he is currently making the most of the NFL offseason and his Chiefs team won’t return for practice until July.

It has been reported that Kelce has made plans for his time with Swift in Europe to help the singer make the most of her downtime between shows.

He has apparently booked tables at some of the finest restaurants across the continent as well as planning to visit vineyards in Italy with her.

Before heading to Singapore, Kelce was on hand to support his brother Jason bringing the curtain down on his NFL career.

Travis wept as he took a seat in the audience for Jason’s announcement and cried again when they discussed it together on their New Heights podcast.

The brothers then took a seat courtside for their hometown NBA team, Cleveland Cavaliers, taking on Boston Celtics on Wednesday night. Jason was honored by the crowd, a little over 24 hours on from his retirement confirmation.

Travis and Swift last saw each other in Australia – Kelce flew to Sydney and they visited a zoo together around her performances Down Under.

Kelce admitted that the media hype in Australia surprised him.
