A wedding guest for the upcoming nuptials of Taylor Swift and Travis Kelce is furious after allegedly being told they’re not allowed to bring a plus-one.

“My invite did not let me bring a plus-one,” an unnamed guest claimed to the Daily Mail on Friday.

“I mean, what am I supposed to do? Go alone? That is so awkward. I don’t think I am going to attend because I don’t want to go by myself and I am not sure I will know too many people there. I mean, sorry, I am not friends with Gigi and Bella Hadid!”

The reported guest also complained that other guests appeared to have been allowed to bring a plus-one to the celebration, which is happening on July 3 in New York City.

“I know Selena Gomez is bringing her husband Benny Blanco, so she has a plus-one, but I am not allowed to have a plus-one because I am a single woman,” the guest added.

“I get it, the venue can probably allow for only so many people, but it’s not the best feeling.”

The alleged invitation request was so offensive to the guest, she said she was mulling over ditching the high-profile nuptials.

 “It’s the wedding of the year, but I may sit this one out because I am shy,” the guest said of the upcoming event — which will take place at a venue only known to guests that morning.

“I get that too, she doesn’t want everyone knowing where she is getting married until the last minute for security reasons,” the insider said.

“Now it is one big guessing game, everyone is wondering where it will be. Probably a massive hotel like the Waldorf Astoria that has amazing security and access,” they added.

The pop star’s friend said she “loves” Swift, wants “the best” for her and “gets it” — but doesn’t wish to come off like a “major complainer,” per the outlet.

A rep for Swift did not immediately respond to Page Six’s request for comment on Friday.

The “Cruel Summer” songstress and Kansas City Chiefs tight end, both 36, became engaged after two years of dating in a romantic backyard proposal last August.

“Your English teacher and your gym teacher are getting married 🧨,” they captioned photos from the intimate moment.

An impressive list of celebrity attendees have reportedly already been invited, including Chiefs coach Andy Reid, Gomez and Gigi — who are part of the bridal party — Zoë Kravitz and Graham Norton.

Meanwhile, the Grammy winning singer has been spotted stepping out in bridal white ensembles for recent outings, seemingly teasing the massive event.
