Real Housewives of New Jersey star Danielle Staub has a sex tape. The mother of two was able to cock block its release for a while, but the tape has been sold and will now be distributed.

Hustler Inc. has the honor of releasing the 75-minute footage of Danielle having sex with a "mystery man." Danielle is also reportedly naked in the tape too. Gasp! Who keeps their clothes on when they bone?

A rep from Hustler tells us the tape was shot last September -- several months after 47-year old Staub first appeared on the Bravo reality show.  The tape is set to be released on June 14.
