The Chiefs tight end then called it a night and headed home in the early hours of Thursday morning.
He was sporting a blue-and-grey patterned shirt, a silver watch and a huge necklace as he took his ride home with some friends accompanying him.
Kelce is a longtime friend of Timberlake, who surprised fans at Wednesday’s show with a shock NSYNC reunion.
The music icon first made a name for himself as a member of NSYNC, who have not performed together for over a decade.
Kelce has been a busy man since helping the Chiefs beat the San Francisco 49ers at last month’s Super Bowl, jetting to Australia and Singapore to support Swift on her Eras Tour.
He also crammed in multiple parties in Las Vegas during that time, heading from Australia back to Sin City to celebrate with the likes of Patrick Mahomes.
Swift herself is currently on a two-month hiatus before her worldwide tour takes to Europe, where she will embark on a grueling four-month stint, beginning in Paris and ending at London’s Wembley Stadium in August.
The pop sensation has recently been relaxing with Kelce at her luxury seven-bedroom pad in LA, which she purchased back in 2015.
The property, now worth an estimated $31.6million, has since become somewhat of a national landmark amid her ever-growing level of fame.
