'Saved By The Bell' Star: My Husband Had No Right to Tape Our Sex

"Saved By The Bell" star Lark Voorhies is gearing up for a fight over what appears to be a sex tape with her estranged husband.

Jimmy Green is bragging to us he has a homemade tape and is angling for a big sale to the highest bidder.

Lark doesn't deny a tape exists but she tells TMZ if he recorded it he did so surreptitiously ... she says she had no idea.

Jimmy begs to differ, telling us she was on board from the get-go, and she can't change her mind now.
