Bittersweet (Blu Cantrell album)  Bittersweet is the second studio album by American R&B singer Blu Cantrell. It was released in the United States on June 24, 2003 by Arista Records. The album debuted at number thirty-seven on the US "Billboard" 200 chart, selling 29,000 units in its opening week, and spawned the international hit single "Breathe". The album did not share the domestic success of previous album "So Blu" (2001), however, unlike Cantrell's debut album, "Bittersweet" managed to reach international markets, performing modestly in certain European nations. It was nominated for a Grammy Award for Best R&B Album at the 46th Grammy Awards, but lost to Luther Vandross' "Dance with My Father".
