Jason Kelce is weighing in on whether or not he thinks Taylor Swift and his brother, Travis Kelce, are lovers after weeks filled with dating rumors — and the NFL star is riling up the internet by joking that the rumors are all "100% true."

During a Wednesday appearance on the WIP Morning Show, the Philadelphia Eagles player opened up about his little brother’s dating life when teasingly asked by the show’s hosts how Travis and Swift were doing.

“I don't really know a lot about what's happening in Travis's love life,” Jason said after admitting that he’d been “blindsided” by a similar question during an appearance the week prior. “You know, his business is his business and I try to stay out of that world.”

The older Kelce fanned the flames by adding, “But having said that, I think he’s doing great and I think it's all 100% true, and I hope this thing goes a mile," before quickly clarifying, "No, I'm joking, I don't know what's happening."

Neither Taylor nor Travis has yet to comment on the rumors, and Jason’s joke comes just weeks after The Messenger reported that the pair were “quietly hanging out,” and just months after the Kansas City Chiefs star first decided to shoot his shot during a stop on Swift’s nation-spanning Eras Tour.

Back in July, Travis revealed the cute and crafty way he tried (and failed) to give Swift his number during an episode of the podcast he hosts with his brother, New Heights with Jason and Travis Kelce.

“I was disappointed that she doesn’t talk before or after her shows, because she has to save her voice for the 44 songs that she sings,” the footballer told his brother Jason Kelce when asked how he enjoyed Swift’s performance. “So I was a little butthurt I didn't get to hand her one of the bracelets I made for her.”

Travis continued, “If you’re up on Taylor Swift concerts, there are friendship bracelets, and I received a bunch of them being there. But I wanted to give Taylor Swift one with my number on it.”

“Your number as in 87 or your phone number?” Jason teased before Travis quipped back, “You know which one.”
