None of the houses were in my name, none of the cars were in my name. Nothing was in my name," she said. "The pre-nup money means nothing to me. I will walk away from the pre-nup if Rosie will give me full custody."She also critiqued O'Donnell and said she has a diametrically opposed method of parenting.In January, Rosie's publicist issued a statement saying the talk show host was leaving the The View and had split from Rounds in November, adding that O'Donnell "is putting her personal health and family first."
