New York - Beyoncé has a stepmother.

Her father and former manager, Mathew Knowles, got married last Sunday. His representative told The Associated Press on Friday that he has wed former model Gena Charmaine Avery in Houston, Texas.

The pair had been engaged for a year and a half.

The 48-year-old Avery is a real estate broker.

The 61-year-old Knowles guided his daughter to superstardom with the group Destiny's Child and later in her solo career; she released her father as her manager in 2011.

Knowles, head of Music World Entertainment, still manages several gospel acts including Grammy-winner Le'Andria Johnson.
