Gwen Stefani was in charge of carpool yesterday, picking up her son Kingston from school in LA. Gavin Rossdale couldn't join Gwen, though, as he was prepping for a taped performance with Guitar Center TV Sessions. Gavin and his band, Bush, played music festivals over the past few months to showcase songs from their upcoming album Sea of Memories, which is out next Tuesday, and this Friday they'll debut a video on VEVO. Gwen's also turned her attention back to music. She spent long hours in the studio over the Summer recording with No Doubt, and she'll likely skip going to NYC for Fashion Week, where her L.A.M.B. line will be presented Sunday, in order to stay focused on the new album.
