The next time Tina Knowles hears her daughter Beyonce's 'Single Ladies,' she may find herself relating more than ever. As TMZ reports, the singer's parents have finally been granted a divorce, some two years after the initial court filing.

In court documents obtained by the gossip website, Tina calls her marriage to Mathew Knowles "insupportable because of discord or conflict of personalities." That may be a fancy way of saying that she was cheated on, as last year, DNA tests revealed that Mathew, Beyonce's former manager, had fathered a child with another woman.

Tina started the divorce proceedings in November 2009, shortly after news of Mathew's infidelity broke, but the case was dismissed the following year, when neither party showed up in court. She refiled this past August, and the final decree came down last month.
