Marriage rumors swirl about Latin heartthrob Enrique Iglesias and tennis champ Anna Kournikova, but the singer envies the unattached lifestyle of his pals who play for the other team. "My stylist is gay and lives in L.A.," he tells the new issue of Genre magazine, on stands July 2, "and when he came to Miami, he went out. And I asked, ‘Your boyfriend doesn't care?' And he said, 'We have an understanding if I'm out of the city.' When I saw George Michael, he said the same thing...I'm going to have to have a talk with my girl!"

What, you weren't invited to the Most Famous People on the Planet Conference at Butter Monday night?

Shortly after Madonna and Janet Jackson left the Lafayette St. hot spot around midnight, two giant black SUVs arrived and disgorged Demi Moore, Ashton Kutcher, Penelope Cruz and Shakira. (It's like the State of the Union Address: At least one high-ranking celebrity has to be in a secure location in case the place is bombed.)

The foursome rolled into the club arm in arm. Ashton dragged Penelope onto the top of a corner booth to dance to '80s hits, while Demi and Shakira whispered to each other on the dance floor.

Later, Demi and Ashton lip-locked to an Annie Lennox song, while Penelope and Shakira got their groove on with engaged NBA superstar Tony Parker. Watch out, Eva Longoria!

If your husband made a million a week, what dumb thing would you spend it on? According to In Touch magazine, Victoria Beckham has designed a $500,000 closet for her new L.A. home. It supposedly features a leather floor, Baccarat crystal chandelier, $80,000 Andy Warhol shoe print, a computer that tracks when she wears items of clothing and a camera to give her a 360-degree "cat scan" of her outfit before she steps out.

NOT everyone buys Cameron Diaz's apology for traipsing around Peru carrying a bag emblazoned with a red star and the words "Serve the People," Communist icon Mao Zedong's most famous political slogan, printed in Chinese. Thor Halvorssen, president of the Human Rights Foundation, told Page Six, "It is bad enough that Diaz wears a bag quoting history's most prolific butcher, but what's even worse is that she is of Cuban heritage and really should know something about the true history of communism. There is a double standard here that boggles the mind: Had she worn a bag quoting Himmler or Pinochet, she would likely face career annihilation, and rightly so." While the Mao bag is ultrachic on the Upper West Side and college campuses, in Peru, the "Serve the People" slogan evokes memories of the bloodthirsty Shining Path terrorists who left nearly 70,000 dead. "I sincerely apologize to anyone I may have inadvertently offended," Diaz said in a statement. "The bag was a purchase I made as a tourist in China, and I did not realize the potentially hurtful nature of the slogan printed on it."

DON'T expect John Stamos to visit Australia again any time soon. The "ER" star was called "bleary-eyed, staggering and slurring," as well as "tired and emotional," by a Sydney newspaper after appearing on several TV shows in a highly disheveled state. Interviewer Kerri-Ann Kennerley noted, "It was a bit like he'd perhaps come from a hotel minibar." In one memorable moment, Stamos likened himself to Elvis Presley and Princess Diana, quipping: "Who else has died? My career after coming to Australia." He later blamed his weird state on jet lag.

CELEBS can expect privacy at the Tower Bar at the Sunset Tower Hotel in L.A. Last week, an entertainment freelance reporter for one of the weeklies was unceremoniously booted after she was caught texting people that Jennifer Aniston was there with her new beau, Paul Colford. "Security was called and she was told to never come back," our insider said. But the journo didn't go quietly - "She made a huge stink and started screaming." As she was being tossed, "The entire bar - including [Aniston], Bernie Brillstein, Kate Hudson and [former Paramount head] Donald Deline - started applauding, and some people even stood up."

THE new face of Nintendo is . . . Nicole Kidman? Nintendo has announced that the star plans to appear in its new "pan-European campaign" for the company's new 60-day Brain Training series. Kidman, 40, said, "I love the concept that Nintendo is reaching out to new audiences with their self-improvement products . . . I've quickly found that training my brain is a great way to keep my mind feeling young." Of course, the airbrushed photos in the ads keep her face looking young, as well.

IS there a beef between Madonna and Janet Jackson? Madge was chummy with fellow singer Shakira at Butter Monday night (our spy said they showed up "hand in hand") and was spotted dancing on banquettes with Demi Moore, Ashton Kutcher and Penelope Cruz. But Jackson was holed up a few booths down and, "She was not invited to join Madonna's crew," said an onlooker, who told us the table drank "seven bottles of champagne and a ton of beer."

The gay singer revealed he has not had a test in over three years while filming for comedian Stephen Fry’s new television show HIV and Me.
