Scarlett Johansson is not pregnant, claims publicist

Get your lowdown on what's happening in the world of Hollywood, right here!

Scarlett Johansson has denied rumours that she is pregnant with Sean Penn's baby.

The actress sparked speculation after she was pictured in Malibu over the weekend looking more curvaceous than usual. The 26-year-old appeared to have a small bump protruding beneath her tight grey vest and black lycra leggings while on a run with her new boyfriend, Sean Penn, 50.

'Scarlett is not pregnant,' the Daily Mail quoted her spokesperson as saying in a statement. She's outside running and it's simply the placement of her shirt that is misleading. She's been training for The Avengers for over four months and is in the best shape of her life.'

The pair were joined for the jog near Penn's Malibu home by friend Owen Wilson, who puffed away behind the couple in a long sleeve T-shirt and shorts -- the boys soon powered ahead though, leaving Scarlett trailing behind in their wake.

Looks like Lady Gaga should buy some flat shoes now.

The singer recently fell flat on her back in front of thousands of fans as she jumped off her piano in the middle of a song.

Leaping off the burning piano onto the stool, her heel accidentally flicked the stool away from her, and Gaga landed flat on her back under the piano. Her outfit of bra and knickers offered no protection, but ever the professional Gaga didn't even miss a note of her hit You And I.

She carried on singing where she lay beneath the piano, having narrowly avoided smashing her head on the keyboard, then crawled to her feet with the microphone still clutched in her hand. The fall came as Gaga performed as part of her Monster's Ball concert in Houston.

'It was in the middle of the show,' the Daily Mail quoted fan Eric Souknary, 18, who shot the video, as saying. 'She was really high up and it looked really bad. I only just managed to keep the video steady. 'The crowd all saw it and I don't think anyone would have minded is she'd walked off the stage to get checked out by medics.

'But she was a real professional and jumped back up on stage to finish her set in front of the fans. 'It was really amazing to see,' Souknary added.

American Idiot, a broadway production that uses the songs of the popular rock band Green Day's seminal 2004 album to tell the coming-of-age story of three small-town guys -- is set to close on April 24 and Milk screenwriter Dustin Lance Black is in talks to write the script for the cinema version with Michael Mayer directing.

It is expected Green Day lead singer Billie Joe Armstrong will be asked to play the role of the drug dealer St Jimmy, Deadline.com reports.

Before the musical opened last year it was optioned by Playtone partners Tom Hanks and Gary Goetzman, who previously turned the stage hit Mamma Mia! into a smash hit movie.

When the musical first came out in 2010, Billie admitted he was very proud and pleased with the production. He said at the time: 'It moves people. I think it's the same reason why you would want to go see a band play live, you know?'

'It's a record that's coming to life, it's in your face, and it's a story. 'That's what American Idiot does. That's what it does in the music, and that's what it does onstage.'

Music mogul Simon Cowell's company Simco -- which produces reality shows The X Factor and America's Got Talent --made $32.4 million in nine months during 2009, according to new figures.

Simon, who is estimated to be worth a huge $164 million -- set up the business in 2002 and sold it to Sony BMG in 2005 for $43million in 2005 on the condition he got a cut of the profits as salary.

According to the Daily Star newspaper, insiders are calling the profitable nine-month period the 'Boyle Factor' because of the huge success of Britain's Got Talent singer Susan Boyle who has since gone on to become a global sensation.

Since the figures were released, Simon has restructured his business and set up a new company called Syco Entertainment Limited which is co-owned by himself and Sony BMG and now owns all of his musical and television assets, including the UK and US versions of The X Factor and the contracts of his superstar artists such as Leona Lewis.

Under the terms of the arrangement Simon earns 50 per cent of everything the company makes, rather than a percentage of the profits, a deal which could see him bank $1 billion over the next six years.

Director James Cameron and 3D systems developer Vince Pace have announced the creation of the Cameron Pace Group, which intends to help studios convert to 3D.

'Our goal is to banish all the perceived and actual barriers to entry that are currently holding back producers, studios and networks from embracing their 3D future,' Cameron said.

The announcement was made at the National Association of Broadcasters meeting in Las Vegas. At a panel discussion on 3D-TV technology, Cameron forecast that 3D TV will really take hold once it can be offered without glasses. 'At that point, I think the people who are first and foremost as leaders of 3-D content creation are going to be the winners in the overall marketplace, the overall broadcast market,' Cameron said.
