Well, we know Whitney Houston‘s mom Cissy wasn’t there (she had her reasons), but a whole lot of other stars turned out for record executive Clive Davis’ annual pre-Grammy party on Saturday, Feb. 9 at the Beverly Hilton.

Katy Perry and John Mayer showed up together, and Miley Cyrus and her side-boobs got in one last showing before the CBS-mandated ban on such things at the actual awards show. Meanwhile, Janelle Monae walked the red carpet in … well, we’re not quite sure WHAT that was, and of course Kathy Griffin made an appearance (probably to gather intel for future comedy routines).

Here are some photos we gathered for you.
