Taylor Swift has been spending her summer away from the public eye, but the “Bad Blood” singer still makes the whole place shimmer when she does choose to make an appearance.

Swifties have been busy sleuthing the star’s secret date nights with boyfriend Travis Kelce as well as her rare girls’ night outings over the past few months—and fans caught Swift stepping out in a plunging LBD to celebrate her BFF Selena Gomez’s birthday over the weekend.

In a photo shared by the Only Murders in the Building actress on Sunday, July 20, Swift could be seen sitting next to her in a pool of metallic balloons.

In contrast to Gomez, who rang in her 33rd birthday in disco-inspired full glam, the “Blank Space” put a preppy spin on the LBD in a simple plunging dress. She paired the long-sleeved black dress with black sheer tights, her signature red lips, and black liquid eyeliner. Swift ditched the natural blonde curls she’s been sporting recently, opting for a sleek straight style with rounded bangs.

She was a sartorial opposite to Gomez, who leaned into the evening’s discotheque theme, courtesy of a mirrored Nadine Merabi jumpsuit paired with a white fuzzy jacket and a Brilliant Earth diamond tennis necklace.

Posing alongside her fiancé Benny Blanco and other attendees like actress Sofia Carson, the “Calm Down” singer accessorized with yellow-tinted sunglasses, a dark smoky eyeshadow with dramatic cat eye eyeliner, and bombshell curls.

It’s the first time the besties have been spotted out together since their May 31 dinner in New York City.

While dining and gossiping together at The Monkey Bar, Swift wore another LBD in a slightly more bejeweled style—a scoopneck minidress embellished with rhinestones along the neckline and hem—paired with sky-high metallic platform sandal heels, a miniscule black purse, and diamonds decorating her ears and arms. A gilded “TNT” friendship bracelet—a sweet nod to her relationship with Kelce—sparkled on her wrist.
