The GOOD News: "Celebrity Rehab" star Kari Ann Peniche is PREGNANT!!
The BAD News: Her husband is unsure if he's the father ... and has filed for a divorce.



TMZ has obtained the divorce papers, in which Justin Williams states that Kari Ann is pregnant -- and wants a judge to order genetic testing to determine if "this is a child of the marriage." The docs were filed in L.A. County Superior Court by Williams' lawyer Marlo Van Oorschot.

Kari Ann has been treated for sex addiction in the past -- even appearing on "Sex Rehab with Dr. Drew" back in 2009.

The couple has only been married for a few months -- they tied the knot back in February.

Calls to Kari Ann have not been returned.

Kari Ann Peniche -- the ex-beauty queen who starred in Season 3 of "Celebrity Rehab" -- tied the knot last Sunday… and TMZ has learned, the minister was a real-life shaman.


Sources tell TMZ, Peniche and her boyfriend Justin Williams were married by spiritual guru Shaman Durek -- an L.A.-based "spiritual guide and gifted healer" -- and it all went down at a non-denominational chapel in San Diego.

We’re told the reception was in a penthouse overlooking downtown SD -- where about 100 guests chowed down on a fancy SEVEN-COURSE French dinner.

Bon appétit!

Another major setback for former "Celebrity Rehab" star Kari Ann Peniche -- TMZ has learned the ex-Playboy model has thrown in the rehab towel again -- this time after only three days.


A rep for Peniche tells us the former model decided to bail on a high-end rehab clinic -- where she was being treated for an addiction to meth.

We're told Kari Ann claims when she checked in -- her boyfriend promised to follow suit soon thereafter. But after day three -- the BF was a no-show ... so Kari Ann left the clinic in search of her guy.

We're told the couple is now working on their relationship -- and Kari Ann does plan to seek further treatment for her meth problem.

Calling Dr. Phil ... or Drew ... or Laura -- (she's not that desperate).

Kari Ann Peniche -- the Playboy model from VH1's "Celebrity Rehab" -- just checked into another rehab center to be treated for an addiction to methamphetamines ... only this time, her progress won't be aired on television.


Sources close to Peniche -- who you may also remember from the Eric Dane/Rebecca Gayheart "naked tape" -- tell us she checked into an expensive, high-end rehab clinic late last night .. and plans to stay for 30 days.

We're told Peniche is prepared to foot the massive bill for the high-class rehab joint ... which we're told will easily exceed $30,000.

Fully dressed and not recording his wife in a tub with another chick, Eric Dane emerged from his home for the first time since that nude threesome video hit the Internet and went to the gym in L.A. yesterday.


The 36-year-old "Grey's Anatomy" star has to keep his body in shape for his next home video movie.

He's only a puppy -- but Kari Ann Peniche's 18-month-old doggie may have already had a dangerous brush with cocaine.



It all went down back in July -- back before Kari Ann's naked threesome tape surfaced with Eric Dane and Rebecca Gayheart. Peniche's house sitter noticed her Pekingese puppy "Buster" began to vomit, experience diarrhea, and twitch uncontrollably.

Kari Ann had a house sitter because she was shooting Dr. Drew's "Sober House" at the time. When she found out her pooch was in distress, she immediately left the rehab facility and rushed home to take him to the vet .

According to the veterinary report obtained by TMZ, Kari Ann told the doc Buster may have been exposed to Xanax, cocaine, methamphetamine or other unknown drugs.

So how would Kari Ann know about Buster's exposure to drugs? It's a mystery. What we do know is that Mindy McCready was living in the house at the time. Mindy told us, "I've never hurt an animal and I don't do any drugs." For the record, Mindy pled guilty in 2004 for using a fake prescription to buy OxyContin.

After the vet ran tests, it was determined Buster was suffering from "unknown toxin/drug exposure." But don't worry, Buster was treated and eventually recovered.

Kari Ann Peniche -- the chick in the Eric Dane/Rebecca Gayheart naked tape -- just sealed the most ironic deal ever: She's gonna be designing clothes.


The lucky fashion house cashing in on her expertise: Christian Audigier, of course. According to the Ed Hardy maestro, Peniche arranged a meeting with him today and they'll be designing a line of swimwear.

We hear Peniche's line will be perfect for any water-based occasion ... especially videotaped bathtub parties.

The other girl in the bizarro 3-person naked romp vid with Eric Dane and Rebecca Gayheart wants everyone to know she was "just having fun with my friends."


Last night at a gas station in West Hollywood, a clothed Kari Ann Peniche told us she's unsure if she'll be taking legal action against her former roommate/singer Mindy McCready -- who Peniche claims stole the tape from their apartment after a dispute over money.

As TMZ first reported, Dane owns the rights to the video and is planning to sue anyone who publishes it.

It didn't take long -- TMZ has learned there's already a legal war raging over the Eric Dane, Rebecca Gayheart naked threesome tape.

Legal pit bull Marty Singer, who reps Dane and Gayheart, tells us he will sue anyone who publishes the video, which he calls "a private, confidential tape."

Singer says he just spoke with third wheel Kari Ann Peniche and asked how the tape got leaked. Her response: "I have no idea. I had nothing to do with it."

As for reports there's a full-blown, uncensored sex version of the tape, Singer said, "From what I've seen it's a naked tape, not a sex tape." Singer added, "At most it's 3 people maybe wanting to have sex."

And that's why we love Marty Singer.

The newest celebrity XXX tape has already hit the Internet -- a threesome -- this one featuring "Grey's Anatomy" star Eric Dane, his wife Rebecca Gayheart and a former beauty queen//Hollywood madam named Kari Ann Peniche.



In the video -- which was first posted by Gawker.com, Gayheart and Dane take turns filming as the naked trio hangs out in Peniche's Southern California apt. It appears they are all seriously inebriated in some way -- at one point Rebecca can be heard saying she needs to lay down because she's so high.

At the end of the tape, Gayheart and Peniche are nude in a bathtub together, while Eric films them. According to Gawker, the 3-minute clip is cut down from roughly 12 minutes of footage.

So far, no statements from anyone's reps.

TMZ LIVE: Harvey answered all your questions today about the Michael Jackson hearing and the Dane/Gayheart sex tape ... check it out!

"Celebrity Rehab with Dr. Drew" -- the show that exploits celebrities who are battling addiction -- is now exploiting a celebrity who has already battled addiction.

We've learned Mackenzie Phillips -- who entered rehab for the 10th time in September 2008 -- will appear on the third season of the show as a "sober coach." Phillips was busted for cocaine in August 2008, but had the majority of the charges against her dropped -- and the final charge will be dropped when she completes a drug diversion program. By all indications, Mackenzie has done a complete 180 and says the arrest saved her life.

The role of "sober coach" on the show was previously played by Gary Busey -- and we know how that turned out.

And we know the other new cast of characters. Let's just say Mackenzie has her work cut out for her.
