Selena Gomez Wishes 'Goddess' Taylor Swift a Happy 34th Birthday with Cute Kissing Selfie

Taylor Swift is feeling the birthday love from her BFF, Selena Gomez.

The Only Murders in the Building actress shared a snap of herself and Swift to mark the singer’s 34th birthday on Wednesday which she captioned, "Happy Birthday to the goddess that is @TaylorSwift." She also added a graphic to her Instagram Story which read "I love you."

The candid image shows the besties posing in a mirror as Swift plants a kiss on 31-year-old Gomez’s cheek. The pair are dressed in coordinating shades of brown, with Swift wearing a turtleneck jumper and plaid mini skirt while a smiling Gomez opted for a matching snakeskin jacket and mini skirt.

Gomez and Swift stepped out in the same outfits on Friday, when they attended a Ramy Youssef comedy show with Cara Delevingne, Anya Taylor-Joy and Zoë Kravitz.

It has been a week filled with celebrations for Swift. The “Cruel Summer” singer celebrated her milestone Wednesday with a night out at N.Y.C. hotspot The Box alongside actress Blake Lively, 36. The pair twinned on the evening in matching black dresses, with Swift opting for a black mini-dress from Clio Peppiat Lucina — made famous in series two of The White Lotus — while the Gossip Girl star opted for a black leather midi.

On Tuesday evening, she and Gomez also stepped out at Parcelle Wine Bar in New York City's Lower East Side, and were later joined by Miles Teller and his wife, Keleigh Sperry for dinner at Zero Bond in Manhattan.

Though the “Shake It Off” singer’s boyfriend Travis Kelce appeared to miss out on celebrations as he was busy in training, friends of the NFL star insist their relationship is the “real deal.”

An insider close to the Kansas City Chiefs tight end exclusively told PEOPLE last month, “This is the real deal for him. [Travis’ friends are] still a little shocked by all of it — that he's dating the Taylor Swift, but they've seen how down to earth she is with his friends and family.”

The source also said the relationship is “growing” because the football player, 34, and the singer have both found success in their own worlds — and continue to appreciate one another's accomplishments.

“They're both really hard workers, and he acknowledges her art is hers, and he has what's his,” the source added. “He understands the territory their relationship comes with and like he said, isn't letting any of the hoopla impact how they're growing together.”

The source concluded, “Their relationship is about the two of them, and he sees Taylor for who she is and vice versa."
