Julia Michaels celebrated her upcoming 25th birthday with a '90s-themed birthday party Sunday night (Nov. 10), and in attendance was her pal Selena Gomez.

The "Lose You to Love Me" songstress, also a '90s baby herself, wore a black midi slip dress, chunky heels and a choker for the festivities. To complete the look, Gomez rocked a pink eyeshadow look, a '90s nude lip with brown lipliner and a messy updo with the signature side pieces hanging loose to frame the face.

Michaels opted for a Cher Horowitz-esque red spaghetti-strap dress for her look. Catch some fun snaps from the party via a fan Twitter account below.
