Williams came into the episode in last place, earning 15 points out of 30 for her foxtrot with professional partner Tony Dovolani. Judges' scores are combined with viewer votes to determine which couple is ousted each week.
Williams is the second contestant eliminated from the hit ABC show's 12th season. Radio host Mike Catherwood was dismissed last week.
Returning to dance on Monday's show will be actors Kirstie Alley, Ralph Macchio and Chelsea Kane; athletes Hines Ward, Chris Jericho and Sugar Ray Leonard; singer Romeo; reality star Kendra Wilkinson and model Petra Nemcova.
