The Coachella music festival was in full swing this weekend, with tons of celebs getting hippied out in Indio... including Sienna Miller and Kelly Osbourne!




Do we like these two together? I dunno yet. They always look annoyed, so I guess they have that in common!

Wonder what Kelly wants us to "speak up" about?
