Travis Kelce’s NFL pal may have inadvertently let it slip that the Kansas City Chiefs tight end and Taylor Swift are secretly married.

Chicago Bears player Cole Kmet’s event planner, Ellie Nottoli, shared details on his Saturday wedding to Emily Jarosz, revealing that Kelce and Swift were on the guest list.

The planner revealed the “personalized touches” at the ceremony, including a letter that was addressed to “Taylor and Travis Kelce” in elegantly calligraphy, with a “Table 13” assignment.

“We all know Taylor and Travis were at a different wedding in Tennessee,” Nottoli said in an Instagram Story video on Monday.

“But each guest had an envelope that was adhered to a beautiful backdrop, and Emily wrote love notes to all of her guests.”

The letter reveal sent several fans into a frenzy over the possibility that Swift and Kelce had already said “I do.”

“TAYLOR AND TRAVIS KELCE?!????? EXUSE [sic] ME,” one person gushed.

However, not everyone was convinced. “This is very common for couples (married and unmarried) for weddings. it’s the aesthetic,” another person wrote.

“Me and my bf do that too on gifts and stuff even though we aren’t married, it’s just kinda for the aesthetic of it,” a third chimed in.

Meanwhile, a fourth quibbled, “technically it should be Travis and Taylor Kelce.”

As it turns out, the NFL star and his pop-star girlfriend weren’t even at Kmet’s wedding, which took place on Saturday. The duo instead hit up Kelce’s cousin Tanner Corum’s wedding on Friday in Knoxville, Tenn.

Corum exchanged vows with Samantha Peck during the countryside wedding.

Social media pics of the famous couple showed the singer, 35, sporting a blue floral strapless dress from Markarian for the occasion, with Kelce, also 35, donning a laid back quarter-sleeved shirt and slacks.

The marriage speculation comes two weeks after a source dropped hints as to when Kelce might pop the question to the songstress.

“Once he is done playing [football], the conversation will be front and center,” an insider told the Daily Mail in May — referring to Kelce’s upcoming return for another NFL season with the Chiefs.

“Everyone is just waiting for Travis to ask her parents for her hand in marriage, her parents will say ‘yes,’ and they can’t wait for them to get engaged,” they continued.

“Nothing seems to be imminent, but it will 100 percent happen.”
