In one shot — which Nina originally posted as an e-birthday card — Julianne is kissing her bestie, and in another, pal Anita Patrickson is wrapping them both into a hug as they smile and/or show their best duck faces.
Though we love the Vampire Diaries starlet, our favorite has to be the one of Selena Gomez looking ready to smooch the camera as Lily Collins (upcoming star of The Mortal Instruments: City of Bones) and Julianne sandwich her. Someone is photobombing in the bottom, but we can’t tell who it is!
Given that Julianne only posted a few photos of her birthday party before, it’s great to see who else was celebrating with her. This is, of course, in addition to her ringing in Selena’s b-day over the weekend, too — with a gypsy theme! Love it.
Check out the trio of photos below, then hit the comments with what you think about all these celeb besties!
