E! News has obtained a copy of the former footballer's divorce filing against the Bravolebrity that was filed on March 22 in Georgia's Fulton County Court. The papers state the couple tied the knot on May 21, 2011, have no minor children together and cited as the reason for the dissolution that their marriage is "irretrievably broken."
Stewart also states that the twosome have no marital assets and asks the court to let him keep his premarital and nonmarital income and assets.
"[Williams] is an able-bodied person, earning income and is capable of supporting herself," notes the petition.
The ex-Pittsburgh Steeler also requests that neither party pay alimony.
