Shauna Sand -- coming to a sex tape near you.

A video of Lorenzo Lamas' ex having relations with her much younger boyfriend (believed to be model Greg Knudson) is set to be released by Vivid Entertainment, but it's not like she's exactly doing press rounds for it.

``Yes I did make a sex tape with my boyfriend earlier this year,'' Sand, 38, told TMZ.com. ``In fact, I've made several sex tapes, but I certainly didn't sign off on this.''

Strange timing -- Leave it to Lamas, E!'s Kardashian-like, family-centered reality show, premiered Sunday night. The former Playboy model, who has three kids with Lorenzo, is featured on it.

Shayne Lamas, Sand's former stepdaughter, says she thinks the move was calculated.

``Isn't that convenient that her tape just happened to be leaked the day after my show premiered?'' said Shayne, who was the winner of The Bachelor, Season 12 (she and the Englishman, Matt Grant, are way over).

NO FOUL PLAY

A Spanish court says autopsy results show Irish Boyzone star Stephen Gately died of natural causes.

A Balearic Islands Superior Tribunal statement released Tuesday says the autopsy shows he died as a result of a pulmonary edema, or fluid in the lungs. There were no signs of violence, and officials add that Gately's body can now be flown home.

Gately was found dead Saturday in a house on the Balearic island of Mallorca.

EXES IN COURT

Jon and Kate Gosselin aren't the only battling exes: Christie Brinkley and ex-husband Peter Cook have reached a temporary settlement in their ongoing custody case.

Cook, 51, had taken the former model to court, but it was Brinkley, 55, who claimed victory.

The architect had requested that: Brinkley undergo anger-management therapy, a parenting coordinator be assigned for the couple's two children and a third party hold the kids' passports. Not happening.

In their 2008 divorce, Cook -- who admitted to an affair with a 19-year-old baby sitter -- received $2.1 million from Brinkley and liberal visitation rights.
