Tom Arnold Files for Divorce from Wife Ashley Groussman

Tom Arnold has officially called it quits on his fourth marriage and filed for divorce after 9-years of marriage.

Arnold filed the documents Wednesday in Los Angeles against Ashley Groussman, after revealing last month that the two had split.

"For the last couple years we grew apart and have been moving in different directions, which is why at this time we have decided to end our marriage," the "True Lies" star said in a statement at the time their breakup was revealed.

Arnold is requesting joint custody of the former couple's two children, Jax and Quinn, and we're told the couple is currently privately mediating a settlement to deal with all the financial details.

In his filing, Arnold did not check any of the boxes regarding spousal support.

Groussman, who married Arnold in 2009, was the star's fourth wife after marriages to Julie Champnella, Shelby Roos and Roseanne Barr.
