Beyonce Knowles' manager father MATHEW is taking credit for the success of former DESTINY'S CHILD singer LeTOYA LUCKETT's debut album, claiming he taught her about hard work during her days in the girl group. Luckett joined the band in 1993, but quit in December 1999, shortly after the release of the girls' sophomore album THE WRITING'S ON THE WALL, which featured the hits SAY MY NAME, JUMPIN', JUMPIN'; and BILLS, BILLS, BILLS. Luckett and bandmate LaTAVIA ROBERSON, who also left the group at the same time, claimed Mathew was keeping a disproportionate share of the band's profits, was too controlling, and unfairly favoured his daughter and the group's fourth singer Kelly Rowland. In 2000, Luckett and Roberson attempted to sue Beyonce and Rowland, before dropped the case, and eventually settled a legal battle with Mathew. When Mathew heard of Luckett's long-awaited success with her self-titled disc, which topped the US album charts earlier this month (AUG06), he insists he was pleased for her, despite past animosity. He says, "I couldn't help but smile. I'm proud of her and her work ethic, something I know comes from DC's early boot camp days."
