Beyoncé is hoping to repeat the huge success of her last album by hooking up with Jay-Z in the studio once again for her sophomore album, B’Day. The debut release is set to be the single Déjà Vu, which features Jigga alongside his beau. The pair will hope to match the success of their 2003 hit, Crazy In Love. Beyoncé finished work on her new album just weeks after wrapping up filming of her upcoming movie, Dreamgirls, which will hit theatres on December 22. Her album however, is set to drop on the singer’s 25th birthday, on September 4 for the rest of the world, and a day later in the US. All tracks are written, arranged and co-produced by the former Destiny’s Child singer. She will also start filming the video for Déjà Vu in the coming months. In related news, B is said to have put Jay-Z on a strict lean protein and vegetable diet, in order to help the rap mogul shed a few pounds. A recent article in In Touch magazine quoted a source as saying, “Beyoncé likes a little meat on his bones, but not too much… [and Jay-Z] was getting chunky.”
