Uma Thurman and Andre Balazs' romance is definitely back on - they have been spotted vacationing together in Denmark. The Pulp Fiction actress, 36, officially split from the 48-year-old hotelier in March - confirmed by her publicist last month. Thurman stunned fans when she turned up the Oscars in March without Balazs, bringing her publicist Robert Garlock instead. But during recent promotional work in the UK for her film My Super Ex-Girlfriend, Thurman hinted their relationship was back on, declaring, "How do you know I've broken up with him? It might very well just be on-and-off again. Who knows?" And the pair were spotted walking hand-in-hand in Danish capital Copenhagen's famous Tivoli Gardens amusement park on Wednesday. After enjoying the sights of Tivoli, the couple were invited by restaurateur Paul Cunningham to dine in his eatery The Paul. Following their meal, the pair rented a pair of bicycles and pedalled through the city, despite the heavy rain. When asked by a photographer if she was on business in Copenhagen, Thurman replied, "I'm just on holiday." Thurman and Balazs - owner of Hollywood's famed Chateau Marmont hotel - first started dating in December 2003, three months after the actress split from her now ex-husband Ethan Hawke. When the pair split in March, Thurman insisted they remain "close friends", while Balasz said they were simply "taking a break".

Troubled Black Hawk Down star Tom Sizemore will star in his own reality show on VH1. The actor will attempt to repair his damaged reputation after several years of bad publicity that has been well documented in the tabloids. Sizemore has had a long battle with drug addiction and was convicted in 2003 of assault and battery against his former girlfriend, ex-Hollywood madam Heidi Fleiss. He was sentenced to 17 months in jail and four months in a drug treatment facility after repeatedly failing drug test last year and was caught using a prosthetic penis sewn into his boxer shorts and filled with a clean urine sample kept warm by a heating pack to fake the results of his drug tests. Also last year, approximately eight hours of celebrity sex tapes were released on the internet starring Sizemore. VH1 senior vice president of series production Jeff Olde says, "You literally watch a man come unglued and unravelled from his own point of view. He lays it all out there." The series will follow the now-sober actor as he embarks on acting jobs, including a movie for the BBC being filmed in Canada. Sizemore will narrate the show, which will also include flashbacks to his battles with drugs and sexual addiction using video footage he shot on his own.

Beyonce Knowles has laughed off rumors she is going to marry boyfriend Jay-Z in a bridal gown modelled after the one the late Princess Diana wore. The singer insists a recent report citing her plans to marry in a replica of the gown are completely absurd. The report also had details of a lavish wedding ceremony, including decorations and catering menus. Knowles says, "I wish I could talk to whoever wrote that, because it's fabulous. Somebody is so creative that they should plan weddings, because they have a great one planned for me and Jay! It even has a menu of caviar. I don't even like caviar!"

Donald Trump has fired his Apprentice sidekick Carolyn Kepcher after she became too enamored with her fame from the show. Kepcher was relieved of her duties as general manager of Trump National Golf Club in Briarcliff, New York earlier this week. Sources tell People that Trump had been unhappy with her performance for some time. The source says, "This has been brewing for over a year. He has tried to get her on the phone, and she was either off giving a speech or was hard to reach." The real estate mogul reportedly felt that Kepcher was promoting her own career more than his golf course. The source adds, "She was supposed to be managing the golf course. She was supposed to be selling memberships. That's her job to sell memberships, and she just wasn't doing it. With the book, the speaking engagements and these endorsement deals, he's looking at that and thinking, 'She's supposed to be working for me. Yet, she is off creating her own empire.'" Trump's representative Jim Dowd's only comment on the firing was, "Mr Trump wishes her the best."

Mel Gibson's shocking anti-Semitic tirade has turned the actor into the brunt of jokes in new comedy movie The Hebrew Hammer 2: Hammer vs. Hitler. Scriptwriters raced to add a note about the Gibson controversy and include it in the sequel of the 2003 Jewish 'blaxploitation' movie. In the new film, an actor depicted as a very drunk Mel Gibson is seen leaving California coastal diner Moonshadows with two blondes a bottle of Irish whiskey. According to news website Tmz.com, the Gibson character berates valets before speeding off in his car, screaming obscenities about the Jews. Apprehended by a traffic cop, just like Gibson was at the end of July, the actor's much-publicized anti-Semitic tirade is cut short when the cop, The Hebrew Hammer, shoots him through the head, before spraying a bloody Star of David onto the windshield of the movie star's Lexus. Screenwriter and director John Kesselman tells Tmz.com, "Young Jews love The Hebrew Hammer. I think if Mel wants to truly extend an olive branch to the Jewish Community as a whole, his on-screen death would go a long way in accomplishing that goal."

Lord of the Rings film-maker Peter Jackson has signed to produce a remake of classic British war film The Dam Busters. Christian Rivers, who animated Jackson's last project King Kong, will direct the film which the Oscar winner insists will be "as authentic as possible and as close to the spirit of the original as possible". The 1954 movie told the true story of bouncing bombs that were developed by the British army to destroy German dams during World War II. It starred Michael Redgrave. Jackson, who enquired about the rights to the story when he was making initial plans for his Lord of the Rings movies, could only make the film after Mel Gibson's Icon production company pulled out. He tells film website ScreenDaily, "(My agent) came back and said that Icon had the rights and that Mel Gibson was going to direct and possibly act in it. Obviously that didn't happen." He adds the new film, which will shoot next year with a $30-40 million budget, will reveal much more about the missions than the original. Jackson says, "So much of it was still secret. They weren't even allowed to show the bomb itself and had to create a fictionalized bomb."
