Selena Gomez turns 33 on Tuesday, July 22, but she gathered up her crew a couple of days early for a weekend bash that appeared to include a balloon pit, some dancing and an amazing Los Angeles rooftop view. Oh yeah, and a Taylor Swift cameo. Check out her Instagram photo dump:

Walsh dressed the Rare Beauty founder in a knit LBD from Self-Portrait, one of Gomez's signature labels on the street style scene. Like Swift, the Only Murders star accessorized with select sparklers—only Gabriel & Co. hoop earrings and her Abril Barret engagement ring.
