New York City Police are investigating former "7th Heaven" star Stephen Collins after learning he has admitted to having exposed himself to three girls, who at the time were all under the age of 14.

TMZ.com says the actor divulged the information during a 2012 therapy session he and his estranged wife, Faye Grant, underwent during their divorce. Collins' earlier admission to Grant prompted the therapist's visit, during which he went into detail about the encounters.

Collins was not aware at the time that he was being taped. His victims included one of his first wife's relatives and another girl, who both lived in New York at the time. Collins said he'd already made amends with a third girl, who lived near hie home in Los Angeles.

TMZ doesn't say when the incidents, which spanned several years, took place. New York City detectives have reportedly traveled to Los Angeles to discuss the tape with Grant.
