The most exclusive after party last night belonged to Beyoncé and Jay-Z

From CNN's Marianne Garvey

There are the Oscars. Then there are the Oscars after parties. Then there are the after after parties.

The night's most exclusive after after party belonged, again, to Beyoncé and Jay-Z. The couple hosted their so-secret-we-can't-even-show-you bash at the famed Chateau Marmont. 

One lucky guest, Reese Witherspoon, at least revealed she was invited.

"Only @beyonce could get me out of the house past 11pm," Witherspoon captioned a party-ready Instagram post.

Other guests reportedly included Charlize Theron, Kourtney Kardashian, Dwayne Wade and Gabrielle Union, James Corden, Jessica Alba, and Spike Lee.

We're guessing our invites got lost in the mail along with those beautiful, orange Ivy Park boxes.
