Tom Arnold separates from third wife

According to the Associated Press — Tom Arnold has filed for legal separation from his third wife, Shelby Roos.  The separation follows four years of marriage.

Documents were filed Monday in Los Angeles Superior Court. Tom Arnold, 47, and Roos, 34, have no children together. They were married in Beverly Hills in 2002.

Arnold was previously married to comic actress Roseanne Barr. They divorced in 1994 after nearly four years of marriage. He was married to Julie Lynne Champnella from 1995 to 1999. 

I’m wondering if Tom is seeing a pattern here?
