Conde Nast Traveler's May "Hot List" issue soiree was held at the Hotel Bel Air on Thursday, and it was packed full of Hollywood's hottest stars! On-again couple Emma Roberts and Chord Overstreet were super affectionate with each other at the bash, hugging and kissing throughout the night.

The Valentine's Day actress was overheard talking about how excited she was for this weekend's Coachella Music Festival, so we're going to guess that the PDA will continue in the desert!

Kristin Cavallari and Jessica Alba bonded over babies, and spent the night chatting all about The Hills star's upcoming arrival as well as the Sin City actress' eco-friendly business The Honest Company.

Celebs really know how to mingle!
