Travis Kelce seemed to have given away a big clue about when his relationship with Taylor Swift started to grow.

The 34-year-old Kansas City Chiefs tight end talked at a press conference on Friday about how he knew what the 33-year-old Grammy-winning artist had worn for Halloween.

“That ’stache and the 87 jersey was pretty iconic there for a little bit,” he told the press about how fans could dress up as him for the scary holiday.

“And I had it when I met Taylor for the first time,” he said.

News from E! News showed that the NFL player debuted his mustache at training camp on August 2, which is when they met. Fans saw the link.

Kelce also talked about other accessories that went with the outfit, like the friendship bracelet that he almost gave to Swift during her July 7 show at his team’s home stadium in Missouri.

At the end of September, when the Anti-Hero singer went to the Kansas City game to support her boyfriend, it looked like they were dating for real.

During Saturday Night Live’s sketch for the season premiere, Kelce and Swift revealed that they were dating.

“Just decided to hit SNL last second and they kinda asked me if I wanted to end the skit that was about me and Taylor’s takeover at the NFL games, which was hilarious,” Kelce told reporters on Friday. “I loved every bit of it. I was laughing my tail off during the skit.”
