And now Robert thinks 16-month-old Cooper deserves a share of the $180,000 trust reserved for Frank's three grandkids.
He and O'Donnell are fighting in court to prove that Frank's will is discriminatory, and in violation of state law.
"Requiring a gay man to marry a woman ... to ensure his child’s bequest is tantamount to expecting him either to live in celibacy, or to engage in extramarital activity with another man, and is therefore contrary to public policy,” the couple's attorney, Anne Bederka, wrote in court papers. “There is no doubt that what [Frank Mandelbaum] has sought to do is induce Robert to marry a woman."
