Katt Williams Wins Back Custody of Daughter — Nanny Tried to Steal My Kid!

Katt Williams just won back custody of his 8-year-old adopted daughter — after the girl”s nanny allegedly lied to a judge to take her away from him … this according to new legal docs.

broke the story last month — a woman named Crystal McGhee went to L.A. court, seeking sole custody of Katt”s daughter … claiming she was the child”s mother.

Katt failed to show up to fight McGhee”s claim — so the judge granted her request by default … on the assumption McGhee was legit.

But Katt just filed new legal docs in L.A. County Superior Court — claiming McGhee”s nothing but a shameless fraud … a former nanny “with no parental rights,” who hasn”t worked with the family for years. The judge has since overturned the previous order.

It”s unclear what motivated McGhee to seek custody — but Katt”s legal docs suggest it has to do with California State parenting perks … i.e. collecting government benefits.

Calls to McGhee were not returned.
