Rosie O'Donnell is moving back to Rockland County, N.Y., says her publicist. The talk show queen had left the area in December, when she sold "Pretty Penny," her 150-year-old, 22-room Nyack mansion that once belonged to legendary actress Helen Hayes, and moved to Greenwich, Conn. -- where Rosie caused a furor in the local kindergarten when she hired an armed guard to escort her son Parker to class. (The problem with the old Hayes house, said Rosie, was that it didn't offer enough privacy or security.) The O'Donnells -- Rosie and adopted children Parker, Chelsea and Blake -- will now reportedly settle in a hilltop home in Valley Cottage, not far from the old Nyack homestead.
