Beyonce Knowles' parents Tina and Mathew have finalised their divorce.

The couple - who were married for 31 years - were issued with a final decree of divorce last month in Texas two years after she filed legal papers to separate from him.

However, the matter was dropped in 2010 after neither party turned up for court.

Tina - who also has daughter Solange with Mathew - re-filed the papers on August 30, and stated the marriage was "insupportable because of discord or conflict of personalities" which "prevents any reasonable expectation of reconciliation".

Tina first filed papers a month after Mathew was hit with a paternity suit by actress Alexsandra White, who gave birth to a son, Nixon, in February in February 2010.

Although he initially denied he was the father, a DNA test later proved Mathew was the child's dad.

Earlier this year, Beyonce - who is currently pregnant with her first child with husband Jay-Z - dropped Mathew as her manager, but admitted she was very thankful for everything he had done for her as both a parent and a mentor.

She said: "I am grateful for everything he has taught me. I grew up watching both he and my mother manage me and own their own businesses. They are hard working entrepreneurs and I will continue to follow in their footsteps.

"He is my father for life and I love my dad dearly. I am grateful for everything he has taught me."
