According to the documents, Tina submitted the divorce filing in McLennan County, Texas on Sept. 24 . The split comes just weeks after Joe -- a former Baptist minister -- was arrested and charged with driving under the influence.
News of the divorce also coincides with a National Enquirer report that Joe recently came out to his family as gay. "Joe got the family together about two months ago and came out of the closet," an alleged insider told the gossip magazine. "He told them that he'd tried to continue in his marriage to Tina, but he couldn't go on any longer and deny the fact that he had these feelings for men. Joe said it wasn't fair to her, and it wasn't fair to him."
According to the source, Jessica and Ashlee did not take the surprise very well. "They asked Joe how long he'd known he was gay, and he said he'd known it for quite awhile. Jessica felt that he'd not only deceived their mom, but her and Ashlee as well."
The story also alleges Joe is engaged in a romantic relationship with a 20-something-year-old man. However, a rep for the Simpson family tells PEOPLE, "It is an amicable split and there is no third party involved. Any other related allegations are completely false."
