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.
