Tom Cruise is terrifying film-makers on the set of Mission: Impossible III, by insisting on carrying out his own death-defying stunts. The superstar actor has refused to allow a stunt double to take on the dangerous high falls necessary for his part as secret agent Ethan Hunt in the sequel - and his willingness to push himself to the limit even scares legendary stunt coordinator Vic Armstrong, who is working on the film with him. Armstrong tells Total Film magazine "He did a 70 foot fall for us last week. He's amazing. He did about seven takes. Absolutely terrifies me - I can see the headlines! What a way to finish a career."

Two and a Half Men star Charlie Sheen has confirmed he and his wife Denise Richards are officially back together by proudly flashing his wedding ring on a US chat show. The actor removed the ring after he and Richards split earlier this year , but the couple has recently been spotted seeking counseling help to save the marriage. And, appearing on Scottish comedian Craig Ferguson's late-night program The Late Late Show last night, Sheen had some happy news. He revealed, "Things are really good and, rather than launching into any specific detail, I can just do that," raising his left hand and showing off his replaced ring.

Kevin Federline boasts about his life with wife Britney Spears and demands to be called "Daddy" in a track from his forthcoming hip-hop debut. The 27-year-old's LP has yet to be released, but a track called "Y'All Ain't Ready" has appeared on the internet. Federline celebrates the lifestyle he shares with Spears and their baby son Sean Preston, but makes an embarrassing slip - confusing the word paparazzi with the surname of opera singer Luciano Pavarotti. He raps, "Back then they called me K-Fed/But you can call me Daddy instead/Go ahead and say whatcha wanna/I'm gonna sell about 2 mil, oh, then I'm a goner/I know you all wish you was in my position/Cause I keep getting' in situations that you wish you was in, cousin/Steppin' in this game and y'all ain't got a clue/Getting anxious? Go take a peep/I'm starrin' in your magazines now every day and week/But maybe baby you can wait and see/Until then all these Pavarottis followin' me."

Boxing legend Muhammad Ali is losing his on-going battle with Parkinson's Disease, according to his daughter Laila Ali. The 63-year-old, dubbed The Greatest, was diagnosed with the disease 20 years ago, and is slowly slipping away from his family. Boxer Laila, 27, explains, "It is painful for me because I would love to sit down and talk to my dad about the way he used to be when he was my age, when he was in his prime, because we are so much alike. I can't really do that. I can't share a lot of things with him. I feel like the disease is progressing. Different things start happening as you get older. I have noticed a change in him, something that goes along with Parkinson's. He has his good days and his bad days. He's taking a lot of different medications. Sometimes, his speech is so slurred, you can't hardly understand him. But he definitely knows what's going on. That's for sure. He sees everything." Ali is currently undergoing therapy for neck and back problems at his home in Berrien Springs, Michigan. His manager Howard Bingham adds, "Laila feels she is slowly losing him."

Teen singer/actress Hilary Duff's mother is being sued for breach of contract by a Canadian clothing firm, alleging Susan Duff violated an exclusive merchandising deal for her daughter's fashion line. NTD Apparel filed a multi-million dollar lawsuit in Los Angeles Superior Court this week, claiming Susan had performed "unlawful, unfair and deceptive business practices" while agreeing sales deals for the Cheaper By The Dozen star's Stuff By Hilary Duff range. The suit also names the family's entertainment company Rafter H as a defendant, alleging they violated an exclusive merchandising agreement with NTD by agreeing side deals with rival retail firms. In response, Rafter H told the New York Daily News the suit was "without merit" and are planning to sue NTD for using low-quality goods in the Stuff collection.

The jury in actor Robert Blake's civil trial are expected to take charge of the case Friday as attorneys wrap up their closing arguments. The Baretta star, who was acquitted of the murder of his wife, Bonnie Lee Bakley, earlier this year is being sued for the wrongful death by his stepchildren. Turning up to the court house in Burbank, California alone yesterday morning, Blake was philosophical about the ongoing trial, stating, "This ain't my first day at the rodeo, it won't be my last day at the rodeo." In court yesterday, Blake took the stand to declare again that he had no hand in the death of his wife.

Oscar winner Jamie Foxx is using TV and press interviews to get another biopic idea off the ground - this time he wants to play ferocious boxer Mike Tyson. The funnyman-turned-actor, a long time friend of Tyson's, portrayed R&B great Ray Charles in hit movie Ray, and now he hopes that by talking about a film about the ear-chomping fighter it will happen. Foxx tells film website Moviehole.net, "I think the Mike Tyson story is the most interesting thing. Nobody knows the stuff that I know, the stuff that I found out. It would blow your mind. Mike Tyson gives you phrases that, if you listen to it, it'll blow your mind. They (media) said 'Mike, how do you feel?' and he said, 'I'm happy. I'm more happy now I don't have any money, ' and they said, 'Why, Michael?' 'I don't have to worry about anything. I'm just here.' And I said, 'That's where you go. Do the story about that and about how he feels now - after he looks back on what all happened." It's not the only biopic Foxx would like to be involved with - he also has his sights set on a movie about tragic soul great Marvin Gaye.

An internet site is offering controversial film maker Vincent Gallo's sperm for sale for $1 million. VGMerchandise.com - which calls itself "the official website for Vincent Gallo merchandise" - includes a detailed agreement whereby wannabe mothers can pay for Gallo to inseminate them by in vitro fertilization (IVF) or even naturally for an extra $500,000, a fee it alleges he will waive if he deems the woman attractive enough. The site details the actor/director's physical attributes: "Mr. Gallo is 5 feet 11 inches and has blue eyes. There are no known genetic deformities in his ancestry and no history of congenital diseases. If you have seen The Brown Bunny, you know the potential size of the genitals if it's a boy (eight inches if he's like his father)." It also recommends his sharp features would "blend well with a softer, more subtly featured female."

Actor Jake Gyllenhaal attacked a co-star after injuring himself when a stunt when wrong on new Gulf War movie Jarhead. Gyllenhaal chipped a tooth after whacking himself in the mouth with a rifle during a scene in which he puts a gun muzzle in a co-star's mouth. He was so incensed he then began showering punches on the unsuspecting, unnamed actor. Gyllenhaal tells gossip site The Scoop, "For some reason. I just got so angry that I had chipped my tooth and just started hitting him and we didn't talk for a month after that." Director Sam Mendes explains the incident, "It's 115 degrees, you're away from trees, cars, everything. You can't hear anything because the wind's blowing. You don't have your clothes, your car, your girlfriend, anything. And I really think Jake forgot he was acting a lot of times."

Tony Award-winning actor Denis O'Hare is considering emigration after his boyfriend was detained as a terror suspect by police at a Virginia airport. The Take Me Out star was returning from his sister's wedding with Hugo Redwood, when their one-way tickets prompted an extra security check. Redwood's ill-advised jest that they were terror suspects led to his temporary arrest, as well as charges of disorderly conduct. But Redwood believes the allegations are ridiculous and unlawful. He says, "The incident report, if you read it, is laughable. It's clearly perjured to cover their asses. The second guard said he heard me shout, 'I'm a damn terrorist,' which is ridiculous. And if this was really about terrorism, why would they not bother to question the person I was flying with?" O'Hare is furious at his partner's treatment and insists president George W. Bush's security paranoia is demeaning the country. He says, "For the first time I feel like leaving the country. America is becoming a nightmare with the permanent war culture brought on by this president. I don't recognize my country."
