Though David Duchovny's publicist surely slapped a "no sex addiction questions" proviso on his public appearances, it's a hard subject to avoid when the show he's promoting is about, y'know, having sex a lot.

Earlier today, America was introduced to Edit Pakay, the tennis coach who allegedly taught beleaguered sex addict David Duchovny more than just a one-handed backhand. "I am not going to deny it," she helpfully told The Mail. "If you want to write that we have an affair then fine. I will not argue against it." Now, though, after an abduction/probe by Duchovny's lawyers, Pakay is doing just that. Go figure! The chatty-yet-confused tennis instructor took the new version of her story to E!:

Like a good episode of The X-Files, David Duchovny's autumn has incorporated one twist after another: shocking revelations (his sex addiction!), creepy, cigarette-smoking men (Billy Bob Thornton!) and now, finally, a guest star who truly is special. Meet Edit Pakay, the actor's 28-year-old tennis instructor, who has given a deliciously rambling interview to The Mail in which she teases that she might have had an affair with Duchovny, though she is eternally quick to back away from the brink of total revelation (also kind of X-Filesy!):

• Madonna's estranged, tell-all-writing brother Chris Ciccone blamed Kabbalah for her divorce from Guy Ritchie. Others, meanwhile, blame Ritchie's "unsympathetic" reaction to her 2005 fall from a horse, which broke eight bones.

It's been a rough year for the Duchovny-Leonis, what with David's well-publicized trip to sex rehab, the general public's crushing indifference to a way-too-late X-Files movie, and the sad lack of bangable extras at the recent Czechoslovakian street fair in Manhattan. Few were surprised when the patient Tea Leoni announced her separation from Duchovny yesterday, but now the Daily Mail is claiming Duchovny instigated the breakup because Leoni was cheating — with Billy Bob Thornton:

• Téa Leoni, who encouraged husband David Duchovny to seek treatment for sex addiction, fell in with Billy Bob Thornton, who has been married five times and has a child with his current girlfriend. Téa became his rock band groupie and accumulated dirty text messages from the actor on her cell phone. She's now separated from Duchovny and free to track down every last sex-addicted actor on the planet. (And Neel Shah is realizing the Truth Was Out There.) [Mail]

♦ Now that Madonna and Guy Ritchie have officially split, the focus is now on her relationship with Alex Rodriguez: Some say he knew that the separation announcement was coming, which is why he's been "lying low" in a five-star Beverly Hills hotel for the past few days. [Us, NYP, E!]
♦ How's Guy doing? Don't worry about him: He could walk away with as much as $250 mil. in a settlement since he and Madonna never had a prenup. [NYP]
♦ A sex tape starring Peter Cook and Diana Bianchi may be out there, although Cook's lawyers are still saying he has "no knowledge" it exists. [P6]
♦ David Duchovny and Tea Leoni have officially split up. We're as shocked as you are [E!]
♦ Raffaello Follieri didn't just swindle adults. He also tricked a 15-year-old girl by promising to get her Anne Hathaway's autograph and then never coming though. Now she's suing him. [NYDN]

We Didn't Want To Believe. Despite having completed his sex-addict's rehab-training certification classes and putting on a brave, united front at aCzechoslovakian street fair, David Duchovny and longtime spouse Tea Leoni have announced their separation: "In light of continuous speculation over the lives and marriage of Tea Leoni and David Duchovny, the couple has confirmed that they have in fact been separated for several months. The couple had hoped to keep this separation private for the sake of their children." [People]

Marc Jacobs standing on the sidewalk outside the Mercer Hotel ... David Duchovny jogging across the street ... Molly Shannon and Nigella Lawson outside ABC studios ... Naomi Watts walking in the West Village with bag from the Container Store ... Salma Hayek and daughter Valentina arriving at their hotel ... Penn Badgley shooting a scene on the Gossip Girl set in Brooklyn ... Katie Holmes carrying Suri out of their East 13th Street apartment building ... Ethan Hawke crossing the street ... Paula Deen and her husband Michael arriving at their hotel ... Beck outside the Letterman show ... Madonna and Alex Rodriguez leaving Yom Kippur services at the Kabbalah Center ... Sarah McLachlan leaving her hotel in Midtown ... and Daniel Radcliffe talking to fans outside the Broadhurst Theater.

As if the borders distinguishing the fictional sex-junkie David Duchovny plays on Californication from the background-player-deflowering poon-addict he plays in real life weren't hazy enough, along comes another wrinkle to further confuse the issue—and this one involves us! On last week's Californication, Duchovny's character Hank is in jail for assaulting a police officer, where he's visited by ex-girlfriend Karen and their teenage daughter, Becca. At one point, Becca holds out an iPhone bearing his mugshot and says, "Check it out: You're on Defamer." Hank responds that he thinks it's "a pretty good picture," and we'd agree—though not nearly as good some others we've run. If your brain hasn't yet collapsed like a deflated beach ball from all the meta-ness, just wait until Tea Leoni stops by HQ to guest edit for a week.

• Saturday Night Live is supposedly working to book Sarah Palin. Producers figure she's good at memorizing lines. [Scoop]

And he's out! After a long, arduous stay in sex rehab, David Duchovny and his wife, Tea Leoni, were snapped at the Czech Street Festival in New York City this weekend. Roger Friedman will be pleased by his choice of coasts, though the actor will certainly have to return to Los Angeles at some point to shoot the soon-to-be-awkward third season of Californication. Tea, might we recommend the newest in fully-transparent glass Star Waggons? [ONTD]

Cougarfornication. Well, this should go well: "David Duchovny, Demi Moore and Amber Heard will form the perfect family in 'The Joneses,' a social commentary with comedic elements." We'd suggest Ashton Kutcher will be a permanent presence on the set, but let's face it—Demi's too old for Duchovny. Which leaves Maxim Hot 100 #21 Heard most at risk. Also a possibility: Kutcher himself. He'd be the alcoholic's equivalent of chugging mouthwash—not ideal, but scratches the itch when there's no real hooch available. [THR]
