Selena Gomez doesn't turn 33 until July 22, but in true celebrity form, the party started the weekend prior. On July 20, the birthday girl shared the Instagram dump to end all IG dumps: photos from her '70s-themed bash.

Taylor Swift attended her BFF Selena Gomez’s 33rd birthday party alongside the latter’s fiancé, Benny Blanco, and other close pals. The “Cruel Summer” songstress was seen posing next to the “Only Murders in the Building” star in a pool of balloons in a photo dump shared via Instagram Sunday from the ’70s disco-themed bash.
