Travis Kelce has signed off on his and Taylor Swift’s relationship nickname — literally.

The Kansas City Chiefs tight end signed a jersey with his number, 87, printed on the back with the name “Swelce” at the top.

The mashup is one of Kelce and Swift’s “ship-names” in addition to “Traylor.”

The red and white custom Chiefs jersey was auctioned off on Chiefs Bid, an NFL-ran auction website where fans can bid on gear signed and/or worn by players.

One lucky fan dished over $500 for the custom jersey.

Kelce and the “Blank Space” singer’s relationship has taken Swifties — and the NFL — by storm since they first confirmed their romance three months ago.

Swift made her first appearance in the stands at Arrowhead Stadium in Kansas City, Mo., on Sept. 24 alongside Kelce’s mother, Donna Kelce.

While fans wondered at the time if this was Swift and the NFL star’s first date, the “Love Song” songstress revealed in her interview with Time Magazine last month that the two had been quietly seeing each other for quite some time.

Swift, 34, told the outlet that she and Travis, also 34, “started hanging out right after” the athlete called her out on his “New Heights” podcast in July.

At the time, he was telling the story of how he attempted — and failed — to pass his number along to Swift through a friendship bracelet while watching one of her Missouri concerts.
