Caillat's new album will be called 'All of You,' but 'I Do' is getting the official single treatment today with it's release to radio. The upbeat, and happy single was written by Caillat and Toby Gad and produced by Greg Wells, and sees a return to form for the singer-songwriter, who won a Grammy for her 2008 duet with Jason Mraz, 'Lucky.' Caillat said 'I Do' is about marriage, but is "supposed to be sort of a joke and is hard to explain."
Along with 'I Do,' Colbie Caillat's new album will also feature special guests, including a track with hip-hop artist Common and a rumored collaboration with Lady Antebellum. 'All of You' hits store shelves May 3.
