A top administrator at Poly Prep Country Day School in Brooklyn has fired back against claims he took two students — including rocker Jon Bon Jovi’s son — on a booze-and stripper-filled trip to Cuba.

Steven Andersen, the head of development at the posh Dyker Heights private school, filed suit in Brooklyn Supreme Court on Tuesday, denying that the December 2012 jaunt was for nefarious reasons and accusing ex-school employee Lisa Della Pietra of lying in a vengeful bid to get him fired.

Andersen admitted he discussed his Cuba trip with Della Pietra, but told her he and the students “were surprised and saddened that seemingly regular young women aggressively had to ask for money” because of economic conditions in the country, according to court papers filed Tuesday.

After a subsequent investigation, “no improper conduct was found,” the suit claims.

Della Pietra sued Poly Prep headmaster David Harman in May for allegedly retaliating against her when she tried to report Andersen’s alleged misconduct. Her suit did not name Andersen as a defendant.

Andersen, who has worked at the school for 38 years, maintained the trip was meant to explore a wrestling exchange program.

Andersen is suing Della Pietra for defamation and intentional infliction of emotional distress.

Della Pietra’s attorney, Anne Vladeck, did not return a call seeking comment.
