Kelly Brook's nude Reebok ad gaffe

Kelly Brook has blasted airbrushing of photographs, while unveiling a giant poster of herself apparently slimmed down by the use of clever shadowing.

The star, 30, made the gaffe while launching a raunchy ad for Reebok. Her nude picture, unveiled at London's Battersea Power Station, appears to have been digitally altered to remove any blemishes.

'Airbrushing has been around since the '50s,' the Daily Star quoted her as telling.

'It's what Hollywood was built on and I'm a big fan of Hollywood and that whole era.

'If people are being slimmed down in photographs then I think that should definitely be pointed out because you don't want to portray something that is unrealistic and unachievable to young teenage girls,' she added.

The huge billboard shows Kelly lying down wearing nothing but a pair of trainers.

She said, 'It's a bit scary having yourself up on a billboard. But I suppose I've got to get used to it because I just did a shoot for Playboy.'

'It seems this month is my naked month,' she added.

Robert Pattinson is on the brink of mental breakdown, it has emerged. The British actor is struggling to deal with being one of the world's biggest stars -- and the constant intrusion into his life, reports Britain's Look magazine.

And sources say Rob's rumoured girlfriend, his Twilight co-star Kristen Stewart, is worried sick.

'Kristen's absolutely frantic about Rob,' Showbiz Spy quoted one insider as saying.

'She's never known him to get so upset. He's gone from obscurity to being one of the biggest stars on the planet and the pressure he's under is unbelievable. She's trying to keep his spirits up but she's worried he needs more support than he lets on,' the insider added.

Meanwhile, it has been claimed that Rob, 24, and Kristen, 20, might quit Hollywood so they can focus on their relationship.

'They are considering changing their lives so they can concentrate on their relationship and get away from stardom,' a source said.

'Kristen suggested they try theatre work and indie films. They are both incredibly talented actors and very well thought of in the industry.

'Despite starring in big-budget productions, they've managed to retain credibility, so theatre is the perfect option,' the source added.
