A woman admitted setting fire to her little girl during a voodoo ritual by pouring flammable liquid on her head and igniting it, scarring her body, prosecutors said.

Marie Lauradin pleaded guilty yesterday to first-degree assault in the horrifying assault on her then-6-year-old daughter at their Queens home in 2009.

The horrifying incident was part of voodoo practice involving a loa, or spirit, prosecutors say.

The judge indicated he’d sentence her to 17 years in prison; she also faces possible deportation back to Haiti.
