The 54-year-old recently hit headlines after he was dismissed from TV series Criminal Minds, and now it's been revealed he has also been experiencing trouble in his private life.

According to legal papers obtained by U.S. news show Extra, Thomas first filed to end his 21-year marriage to his wife Christine in 2014, stating: "The marriage has become insupportable because of discord or conflict of personalities... that destroys the legitimate ends of the marriage relationship and prevents any reasonable expectation of reconciliation."

Christine disputed the allegations and responded by lodging a "general denial", but Thomas challenged the claims in December (15), confirming his wish to legally end the union.

However, no filings have been made since and if the case remains unchanged, the divorce petition will be dismissed on 25 October (16), reports the publication.

Gibson's representatives have yet to comment on the marriage breakdown, which emerges days after show bosses at ABC Studios and CBS Studios dropped him from his leading role on Criminal Minds.

The star, who had portrayed FBI agent Aaron Hotchner since the series began in 2005, was initially suspended from the crime drama after he allegedly kicked a writer in the leg during an altercation in July (16). His exit was made permanent on 12 August (16).
