Cameron Diaz has slammed reports she is cheating on long-term lover Justin Timberlake with her travel show producer Shane Nickerson. Witness Oscar Duran told a US magazine he saw Diaz French-kissing Nickerson - who produces the actress' MTV show Trippin' - outside a Santa Monica, California studio last Wednesday. Duran says, "Cameron wrapped her arms around the guy and started kissing him on the mouth. They stood kissing for a good three minutes." Diaz, 32, and Timberlake, 24, will celebrate their two-year anniversary this month, while Nickerson has a one-year-old daughter Lucy with his wife Elisa. British newspaper The Sun reports that, when asked for comment about the alleged smooch, Nickerson replied, "Oh no, I can't talk to you. You'll have to talk to MTV." However the Charlie's Angels beauty's publicist Brad Cafarelli insists, "Shane Nickerson is a friend of Cameron's and a valued associate who works with her on her MTV show. They do not have any sort of romantic relationship whatsoever."

Monster-in-Law beauty Jennifer Lopez has dumped a behind-the-scenes documentary, after she was reportedly filmed shouting at the crew. The singer's record label Sony secured director D A Pennebaker - who shot Bob Dylan's acclaimed documentary Don't Look Back - to film the superstar making her Rebirth album. But Lopez was unhappy with the end result - even though Sony executives and her managers thought the film was perfect, reports America's Radar magazine. A source says, "Sony was thrilled with the finished product. So too were J.Lo's managers, who felt it captured the Jennifer they knew so well. She was 'stunned' by her depiction, complaining angrily about the sound of her voice and about scenes showing her abusing his employees." Pennebaker has confirmed he filmed Lopez, but refused to comment on Radar's claims.

An unseen Michael Jackson video became key evidence in the pop star's child molestation trial yesterday as footage journalist Martin Bashir left out of his damning Living With Michael Jackson documentary was aired in court. A film shot by Jackson's videographer, featuring his candid chats with Bashir, was shown to the jury as the defense team attempted to prove the pop star had been misrepresented in the TV special. In the footage, Bashir actually praises Jackson's parenting skills - even though he criticized the pop star in the actual documentary. In the videographer's version of events, Bashir told Jackson, "Your relationship to your children is spectacular. It almost makes me weep." Jackson insisted his videographer catch his interviews with Bashir to make sure he wasn't misrepresented. The pop star added, "I haven't been betrayed or deceived by children. Adults have let me down. I'm not a nut. I'm very smart. You can't come this far and be a nut."

Comedian Bill Cosby admits he gave his sexual misconduct accuser a blueberry muffin and an allergy medication, but insists there was no inappropriate behavior. Canadian Andrea Constand accused Cosby of drugging and sexually assaulting her in January - a year after the alleged incident in his Pennsylvania home. In court papers filed in Pennsylvania and obtained by US news show Celebrity Justice, Cosby admits inviting Constand to his home and giving her over-the-counter antihistamine Benadryl when she confessed she was having trouble sleeping. In the papers, Cosby denies assaulting Constand, who spent the night in his home. He admits he woke her in the morning and treated her to a muffin and a cup of tea before she left. Cosby faces allegations from another 12 women, who all claim the comic drugged and molested them.

Dame Elizabeth Taylor has cancelled her appearance at the Cannes Film Festival, prompting fears about her health. The acting legend usually attends an annual charity dinner organized by the American Foundation For AIDS Research (AMFAR), which always coincides with the South of France festival. However, Taylor - who pulled out last year due to health problems - has been replaced by Sharon Stone and Liza Minnelli at the glitzy gala on Thursday. And sources say frail Taylor made her decision not to attend months ago: "Dame Elizabeth Taylor was never supposed to come this year. She will just be there by thoughts."

Rush Hour star Chris Tucker has pleaded guilty to speeding and eluding police during a brief car chase last month. The 32-year-old comedian told authorities that he didn't hear their sirens because he was on his way to church. Tucker entered the pleas on Tuesday in Georgia's Warren County Probate Court and paid a fine of $6,999, according to court clerk Jeremy Moore. Tucker was driving a Bentley at 109 miles-per-hour on a stretch of road with a 70-miles-per-hour speed limit on April 17 when Georgia State Patrol troopers attempted to pull him over, says Moore. The pursuit lasted for about 10 miles before Atlanta native Tucker stopped, according to Moore. The star later told police he was traveling from Atlanta to Columbia, South Carolina, to go to church.

Sienna Miller has been ditched from upcoming movie Factory Girl in which she had been set to play 1960s wild child Edie Sedgwick. The shock decision is a devastating blow to Jude Law's 23-year-old girlfriend - who couldn't wait to begin work on what would have been her first leading role. But movie bosses decided they needed a "bigger name" to portray the drug- addled society darling - who was a muse of legendary pop artist Andy Warhol and rocker Bob Dylan. A source tells British tabloid the Daily Mirror, "Of course she's bitterly disappointed. Who wouldn't be? It's set to be a really shocking film but she was up for it, even the possibility of graphic sex scenes. She wanted to prove to people she's not just a boho fashion icon but a credible actress. Sienna's in rehearsals for As You Like It - she'll bounce back. She is the woman of the moment so she's not short of offers."

Desperate Housewives star James Denton has accused a Los Angeles newspaper of "sensationalizing" his plans to move house in an effort to escape his gawking fans. Denton recently revealed that he's leaving his Glendale, California, house of less than two months after Us Weekly published a picture of the front of his abode - leading local fans to work out where he lived and pay him unwanted visits. And Denton is appalled with a Daily News article - published yesterday and carrying the headline "Desperate Houseseller" - which includes quotes from him and his neighbors. He says, "It sounds a little paranoid and they actually sensationalized it, I was gonna say a little, but a lot. We've had some people stop by and it's not that big a deal but when you have a kid you wanna take some precautions. A national magazine ran a picture of the front of our house and I don't live in a compound, as you know. It's right there on the street. There's not even a gate."
