Inside all of this weekend's hottest, celebrity-filled Coachella parties

For some, the three-day Coachella Music Festival in Indio, Calif., is as much about the parties as it is the music.

And instead of giant parties, this year's festival "saw a new set of unofficially affiliated parties that largely mark a move toward the more intimate and targeted," noted BizBash.

Aaron Paul, Katy Perry, Paris Hilton, Zoe Kravitz, Julianne Hough, and other celebs - including tons of models - all took advantage of this weekend's hottest bashes.
