Mathew KnowlesMathew Knowles has been ordered to cough up monthly child support payments for the son that he has yet to prove is his. According to TMZ.com, a Los Angeles judge has temporarily ordered Knowles to pay the newborn's mother, Alexsandra Wright, $8,200 a month in child support plus cover 100 percent of uninsured medical fees. Additionally, the father to both Beyonce and her younger sister Solange, must pay Wright $20,750 for the month of January, despite reportedly forking over $10,000 before the child's birth to cover medical costs.

Wright, who claims to have had an 18-month relationship with the 59-year-old, filed a paternity suit against him in a Los Angeles Superior Court last year. She gave birth to the child, named Nixon, on Feb. 4.

Although Knowles has yet to confirm the rumored relationship, he filed for divorce from his wife around the same time that stories of his infidelity hit the news circuit. No specific reason was given for the split, but the former couple publicly vowed to remain "good friends" as well as "business partners." Knowles is scheduled to take a paternity test March 1.
