Miley Cyrus was a notable no-show at her own party following Sunday's (Aug. 25) MTV Video Music Awards, and it's not for the reason you think.

No, it wasn't because she didn't want to have to explain to friends and family her twerk-heavy, crotch-grabbing, tongue-hanging VMAs performance with Robin Thicke earlier in the night -- she was in the studio with Kanye West!

The New York Post reports that Miley missed her after-party at New York City hotspot No. 8 to join Kanye for a "top-secret" collaboration. The late-night studio session was said to be for a remix of Yeezy's 'Black Skinhead.' Rumors have the track appearing on a remix EP dropping later this year.

If the report is true, that's a lot of personality in one small room -- ah, to be a fly on the studio wall! While we wait for the collabo to be confirmed, adding fuel to the rumor is the fact that Kanye was also missing in all the after-party action.
