A paternity test has confirmed that Mathew Knowles, 58, is the father of Alexsandra Wright's new baby boy, Nixon TMZ reports. The baby's half-sisters Beyoncé and Solange are 29 and 24, respectively.
The news comes after the elder Knowles initially had no comment about claims that he fathered a child with Wright, an actress, who said they had an 18-month affair with Knowles and filed a paternity suit last October.
Knowles was the manager of daughter Beyoncé, who first rose to stardom with Destiny's Child under his leadership. He split with former wife Tina after nearly 30 years of marriage when rumors of his affair with Wright surfaced.
A rep for Matthew Knowles had no comment.
