Last night was major key at Nightingale Plaza!

Arriving in a Rolls Royce, DJ Khaled was feeling awfully goofy last night when he headed into West Hollywood's brand-new hotspot. Wearing oversized sweatpants and a sweatshirt, the music man had all eyes on him when he posed in some wacky positions for some selfies. BTW: can we please put the athleisure style to bed?!

The venue was jam-packed with D-list celebs like Sofiia Richie, Bella Thorne, Sean Stewart (who was nursing a broken arm) and Tara Reid, itching to hear Khaled perform with special guest Travis Scott.

You know if Tara's there -- a club's gotta be bangin'! The party girl was with her new spiky-haired beau whom she was lovin' up on. Tara wasn't the only celeb who had a new man.

"It" girl Sofia Richie, wearing jeans and a cut-off sweatshirt, and a cut off had a new guy at her side, YouTube star Cameron Dallas -- bye, bye Bieber! The teen showed off the gorgeous guy at the hotspot.
