Selena Gomez will reportedly play a special role in Taylor Swift and Travis Kelce's upcoming wedding, serving as a bridesmaid for her close friend of nearly two decades.

The pop superstar and Kansas City Chiefs tight end kicked off their wedding celebrations with a rehearsal dinner at New York City's Madison Square Garden on Thursday, according to multiple reports . The couple is set to tie the knot on Friday, July 3, at the iconic venue.

Gomez was spotted attending the rehearsal dinner and shared a glimpse of her preparations on Instagram Stories, posting a video of herself in a black strapless Oscar de la Renta gown paired with Jimmy Choo heels . She also shared a photo with her husband, music producer Benny Blanco, writing, "I wish Benny was here rn" .

The bridesmaid role comes as little surprise to fans who have followed the friendship between Swift and Gomez since 2008. The two first connected while Gomez was dating Nick Jonas and Swift was in a relationship with his brother, Joe Jonas . Gomez later reflected on their meeting, saying, "It was amazing, because she was the girl with the big curly hair and all the bracelets and the cowboy boots. We just clicked" .

Over the years, the pair have supported each other through career milestones, award shows, and personal challenges. They have also shared the stage on multiple occasions, including in 2011 when Gomez joined Swift during her Speak Now tour at Madison Square Garden for a performance of "Who Says" .

Swift has spoken about the endurance of their friendship, calling it "very precious and rare" during a 2014 interview . Gomez has similarly praised Swift for never judging her decisions and for offering unwavering support through difficult moments .

The friendship has continued to deepen in recent years. Swift attended Gomez's wedding to Blanco in September of last year and delivered a speech at the celebration . Gomez has also revealed that Swift's song "Dorothea" was inspired by her, and that Swift wrote an unreleased track about their friendship titled "Family" .

In addition to Gomez, several other celebrities are expected to attend the wedding festivities, including Ed Sheeran, Gigi Hadid, the Haim sisters, Suki Waterhouse, Cara Delevingne, Mariska Hargitay, and Kansas City Chiefs coach Andy Reid . The guest list is also expected to include members of Kelce's Chiefs teammates .

Reports indicate that security is extremely tight for the event, with guests reportedly asked to sign non-disclosure agreements and avoid carrying phones inside the venue . Neither Swift nor Gomez has publicly confirmed the bridesmaid reports .
