Monday night, Beyoncé celebrated B'Day with a Soul Train-themed party, while we all watched in tears from our Instagram timelines. The celebration was literally filled with Hollywood A-listers who seemed to have enjoyed themselves to the fullest!

LaLa and Carmelo Anthony were there!

She even walked the soul train line with her mom.

Kelly Rowland and Lala brought the metallic realness.

Solange brought her A-game, as usual.

Chloe x Halle slayed our existence.

Michelle Williams didn't shy away from bold, striped bell-bottoms and a fierce bang.

And Diddy was doing a lot, accompanied by Cassie who showed out herself. 

Overall it looks like this was a night to be remembered! We'll pretend our invite got lost in the mail, Bey, it's alright
