Lawrence Taylor’s arrest for having had sex with an underage hooker hit him in the wallet — so he can’t afford $456 a week in child support for his ailing 13-year-old daughter, the ex-Giant great claims in papers filed in family court last week in New Jersey.

“My income is generated solely by my popularity as a celebrity,” he says in the Bergen County filing. “The fact that I last played in 1993 and legal problems in Rockland County . . . have severely diminished my ability to obtain income.

“I have no college degree or special skills other than athletics,” he notes.

The NFL Hall of Famer filed after Ebony Washington asked for higher payments for their daughter, Erielle, recently diagnosed with Crohn’s disease. Taylor countered that he needs to lower the payments.
