Were Mike Tyson and Vanessa Williams ever married?

You might be thinking of Robin Givens.

"Williams is Catholic. She has been married twice. Her first marriage, to her then-manager Ramon Hervey II, was from 1987 to 1997. They have three children: Melanie (born 1987), Jillian (born 1989), and Devin (born 1993).

Her second marriage was to former NBA basketball player Rick Fox. They married in September 1999 and have a daughter, Sasha Gabriella (born May 2000). After The National Enquirer published pictures of Fox kissing another woman in mid-2004, Fox's representative announced that the couple had been "headed toward divorce" for over a year. A few months later in August 2004, Fox filed for divorce. During some press interviews, Williams cast some doubt on the divorce status, but while visiting the Howard Stern radio show in March 2005, she said that while she and Fox were intimate with each other briefly during the 2004 holidays, a reconciliation was unlikely."
