The "In Crowd" was in full effect last night!

Justin Bieber, Kendall Jenner, Hailey Baldwin, Kaia Gerber, Jaden Smith, and many more famous faces came out to celebrate pal Moises Arias' birthday at Cafe Gratitude in Beverly Hills last night, and it looked like quite the bash!

We're wondering how Selena Gomez feels about The Biebs hanging out with his ex? We know that she flipped out months ago when she learned they had been texting, so we doubt she's thrilled about this meet up. Something that might make her happier? JB has reportedly cut off his brief fling with model Baskin Champion!

Practically this whole group was at Coachella last weekend, so there couldn't have been a shortage of things to talk about over their meal.

Earlier in the night, the "Sorry" crooner went to church to get his praying on before hitting the town, and he really never misses a service.

Where was our invite?
