Travis Kelce takes his role as a boyfriend very seriously. Since December 13 is not just Taylor Swift’s birthday but also her lucky number, Swifties view it as the equivalent of a government holiday. While everyone is anxiously awaiting the big day, Kelce is apparently organizing a spectacular birthday celebration for America’s pop sensation.

While taking a break from the Eras Tour, Taylor Swift has been spending a lot of time in Kansas City, where Travis Kelce is based, and visiting New York City on a regular basis to hang out with pals. It appears that things are going very well for the pair based on the adorable photos of them that have been making the rounds online. One recent photo shows Swift pecking Kelce on the cheek.

But let’s get back to the birthday! As time runs out, Kelce “wants to throw the best party possible” for his famous girlfriend, a source close to the player told Us Weekly. According to the insider, Swift’s closest celebrity friends—likely Selena Gomez, Emma Stone, Jack Antonoff, Blake Lively, and the entire gang—will all be attending the party, which is expected to take place in New York City. They said, “Money is not an object.”

According to a second insider who spoke with Life & Style, Kelce and Swift are organizing a “intimate” meal before the get-together with pals. Friends are hoping Kelce pops the question that evening. “He’s arranged a very intimate, romantic dinner just for the two of them, and is also trying to pull off a semi-surprise party with the help of some of her closest friends,” the insider added. (You probably don’t need reminding that this is an unidentified source, so proceed with extreme caution when interpreting that anecdote.)

Since Swift calls herself a “Mastermind,” it’s no minor accomplishment if Kelce is able to pull off a real surprise party. We’ll be alert and on the lookout for any clues about the December 13 events.
