Known as the former Destiny's Child manager, Matthew Knowles, father of Beyonce and Solange Knowles, is now being sued by his alleged baby mama, TaQoya Branscomb. TMZ reports that back in 2001, the Branscomb and Matthew's younger daughter "hung out together on multiples occasions in nightclubs and bars in Houston."

Solange was completely in the dark that her friend is sleeping with his father and got her pregnant in 2010, around the time when Beyonce's mom, Tina Knowles, is filing a divorce that ended three decades of their marriage life. The 28-year-old singer/songwriter met TaQoya in 2008 through a stylist friend and now she is asking for a DNA test and a declaration of paternity so she can ask for child support to her father.

Aside from child support, 30-year-old real estate agent is asking Knowles for attorney fees as she fights for her daughter's right when she started an affair with him during the time when he fathered another child. "Branscomb tells us she was a lingerie model but is now a real estate agent," TMZ reports who broke the news about Knowles recent legal suit.

Slammed with another paternity suit, Matthew Knowles was sued for a child support by Alexsandra Wright that led to his divorce from his wife. After he acknowledge Wright's son, Beyonce fired her father as a manager and the judge drastically reduced his child support payment from $12,000 to 2,485 due to change of income.

After the elevator scandal, divorce and cheating allegations, Beyonce is hit by another issue about her father. Currently on her "On the Run" tour with rapper husband Jay Z, the "Drunk on Love" singer is keeping quiet regarding her rocky marriage and her father second paternity suit.

After the trio made a joint statement, none of them are mentioning about the elevator brawl, and even Solange is sticking on their statement on her latest interview with Lucky Magazine. "What's important is that my family and I are all good. What we had to say collectively was in the statement that we put out, and we all feel at peace with that," she said in the magazine's August cover issue.
