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.

“So we actually had a significant amount of time that no one knew, which I’m grateful for, because we got to get to know each other,” Swift shared.

Travis has also gushed over the “Lavender Haze” songstress a handful of times.

“Obviously I’ve never dated anyone with that kind of aura about them … I’ve never dealt with it,” Kelce said in an interview with WSJ. Magazine last month.

“But at the same time, I’m not running away from any of it…. The scrutiny she gets, how much she has a magnifying glass on her, every single day, paparazzi outside her house, outside every restaurant she goes to, after every flight she gets off, and she’s just living, enjoying life.”

As the holiday season is among us, Page Six confirmed that Swift will be at Travis’ Christmas Day football game against the Las Vegas Raiders at Arrowhead Stadium and the athlete’s New Year’s Day game as well.

“She’ll for sure be at the games,” an insider told us.
