Beyonce Knowles' father has slammed reports he claimed to be managing his daughter's DREAMGIRLS co-star JENNIFER HUDSON. Media reports have suggested a rift between the two female co-stars, which may have started with Beyonce's father, MATHEW KNOWLES. According to E! Online, Knowles tried unsuccessfully to sign the former American Idol contestant as a client to his Houston, Texas-based Music World Entertainment management. A source says, "He tried to sign her halfway through the production of Dreamgirls, because he wanted to be her manager, but Jennifer turned him down. That's when things really went south. "He walks around saying he's her manager, and everyone is like, 'No, you're not.'" A representative for Knowles insists Mathew never claimed to be Hudson's manager, although he did try to sign the rising superstar to his music label. In the end, Hudson eventually signed with music legend Clive Davis.
