Justin Bieber Teasing "What Do You Mean" Video

While a practical who's who of music (and otherwise) celebrities — from Chris Martin to Ellen to Tori Kelly to Alanis Morissette — taking part in a daily countdown to the August 28 launch of Justin Bieber's comeback single "What Do You Mean," all reports seem to indicate the video will be just as massive and well planned.

While lots of details are under wraps, we know it's a multiple day shoot that has a guest spot for actor John Leguizamo, and more rain than East Los Angeles has seen in maybe forever — and with big screen director Brad Furman on the other side of the camera.

Keep watch on the Bieber tick tock clock for the when the song (and maybe the video) will drop...
