Hosted by May’s cover girl Chloe Moretz, the Carrie star looked gorgeous in something that we’re not exactly used to seeing her wear –- a pink dress! The 16-year-old has gained a reputation as kind of a badass in Tinseltown, but she totally girled it up in her Chloe Sevigny dress for her hosting duties.

Inside the party, Adam Lambert, Jaden Smith and Teen Wolf stars Holland Roden and Crystal Reed kicked back by the pool -- but wait, what’s this we see? Pretty Little Liars co-stars Ashley and Tyler Blackburn looked pretty cozy together, especially with Tyler laying a smooch on Ash’s cheek.

Ashey, donned in several all-natural horn bangles by contemporary jewelry designer Zeffiria and Tyler keeping it simple in a white t-shirt and jeans, certainly look like more than friends, right?  We’ve been thinking these two have been together ever since Coachella last month but hey, we’re going to listen to them and say that they’re “just friends”… at least for now.
