Deion Sanders Files for Divorce

He told you he was gonna do it ... and now TMZ has learned, Deion Sanders has officially filed for divorce from his wife Pilar.

In the documents, Deion states he and Pilar "ceased to live together as husband and wife" on Dec. 21, the date the petition for divorce was filed in Texas.

Deion continues, "The marriage has become insupportable because of discord or conflict" ... which "prevents any reasonable expectation of reconciliation."

Deion announced his intentions to get divorced earlier this month -- claiming, "Pilar and I have decided to end our marriage and move on to the next phase of our individual lives with mutual respect."

Deion and Pilar were married on May 21, 1999. They have 3 children together. Attempts to reach Pilar were unsuccessful.
