There’s a new addition to the Knowles family. Beyoncé and Solange’s father, Mathew Knowles, has been named the father of a baby boy.

According to TMZ, a DNA test has confirmed reports that Knowles is the father of Nixon, his first son, born February 4. The mother is Alexsandra Wright, who claims she had an 18-month affair with the music executive.

Wright filed a paternity suit against Knowles in October. He was temporarily ordered to pay $8,200 in monthly child support until a settlement is reached.

Beyoncé’s mother, Tina Knowles, filed for divorce from her husband of over 30 years last fall after being separated since January 2009. They have two daughters together, Beyoncé, 28, and Solange, 23.
