The claws are still out among the stars of Real Housewives of New Jersey.

As Hustler Inc. prepares to release a sex tape starring controversial Housewives star Danielle Staub, her costar and old pal Jacqueline Laurita has a bold accusation.

Laurita Tweeted late Tuesday: "Heard from a VERY reliable source that D released her OWN sex tape. Heard it's disgusting. Such disregard 4 her kids. I feel horrible 4 them"

Explicit new stills and video clips of Staub -- topless, giggling and frolicking with an unidentified man -- hit the web on Wednesday.

Porn company Hustler has said that 47-year-old Staub, a mother of two, is aware that the tape is being released.

A married mother of three, Laurita was Staub's biggest defender on the first season of Real Housewives of New Jersey, but the old friends have since become estranged.

Staub hasn't yet spoken out specifically about the sex tape scandal. She Tweeted Tuesday: " Having a beautiful day In spite of all that's going on Love my life!! Love my fans !!!! Thanks for being true to me :)"
