BEYONCE’S PARENTS FINALIZE DIVORCE

Mathew and Tina Knowles' on again-off again divorce dragged on for two years, but it's now legally kaput, done, over ... final.

The final decree of divorce was issued last month in a Texas court, and according to documents -- obtained by TMZ -- Beyonce's mom refiled on August 30. Tina's first swing at the divorce was in November 2009 ... but the matter was dropped in 2010 when they were both no-shows for court.
