Stephen Collins and Faye Grant are embroiled in a bitter divorce battle.
According to the official legal documents, over $14 million is at stake, most of it earned by the veteran TV actor.
For this reason, an attorney for Collins states, Grant has been trying to blackmail his client by threatening to expose an audio recording she made of Collins speaking in a 2012 therapy session.
The tape - listen to it HERE - clearly features this former 7th Heaven star admitting to three cases of sexual molestation, including one in which he placed an 11-year old girl's hand on his penis.
Grant has already denied leaking the tape and, in a statement released on Wednesday, she also fought back against claims of extortion.
