The actress and TV personality filed for divorce from Rounds in February (15), after almost three years of marriage.

O'Donnell and Rounds share two year old daughter Dakota, who they adopted together, but Michelle is filing for primary custody.

Rounds' attorney, William D. London, tells the New York Post, "My client Michelle Rounds has decided to start proceedings for sole custody of their daughter Dakota, since it is unequivocally in their child's best interest and general welfare."

O'Donnell's spokesperson, Cindi Berger, is slamming Rounds' legal move, stating, "This is an absurd and desperate attempt to use a child for her own gain."
