Melbourne, Feb 25 (ANI): A shocking TV documentary airing untold secrets about David and Victoria Beckham has reportedly made the celebrity couple see red, as it might just shatter their future success in the US.

In an interview to the UK magazine Daily Star, the couple's friends have insisted that Posh and Becks have been "betrayed" by former friends, lovers, business aides and old school chums in the hour-long program.

"They are spitting blood. They feel they've been stitched-up betrayed, even. This couldn't have come at a worse time, with both of them trying to build new careers and reputations in Los Angeles. They have come under criticism from some observers in the States recently but public opinion is still good. Depending on the exact content of this documentary, that could change," The Daily Telegraph quoted a source close to the couple, a saying.

The show by cable network E! Entertainment, namely 'True Hollywood Story: Posh And Becks' has revealed shocking stories about the couple.

Many embarrassing secrets were uncovered during the course of the programme. One such secret was that Posh was taunted at a performance arts school for being "too fat" and "too spotty".

The documentary showed the Victoria's ex-love Mark Wood, who she dumped after becoming a Spice Girl, claimed she starved herself.

"Victoria didn't really eat anything other than crisps, carrots and apples and drink loads of water. She just looked so ill to me. She lost so much weight," he told in the documentary.

It was also revealed how the Spice Girls cruelly dumped their manager Chris Herbert for image guru Simon Fuller when they were getting famous.

It was shown that she had a controlling influence over Becks which ruined his relationship with Sir Alex Ferguson and ended his Manchester United career.

In fact, the documentary concluded with their unofficial biographer Andrew Morton criticising them for engineering publicity that has often rebounded, making them sink into the dark side of celebrity.

Meanwhile, Posh is said to be painfully embarrassed by the documentary dwelling on her husband's alleged affair with his personal assistant Rebecca Loos in Spain when he played for Real Madrid.

She is believed to be cringing after watching an interview filmed before the Spice Girls recent reunion, in which she admits: "I never actually did that much other than wear the nice clothes and pout, so it wasn't that demanding being Posh Spice, to be honest.''

The programme made fun of the couple's wedding, at which they wore crowns and received guests while sitting on giant thrones.

"They are furious over the way it makes them look. She is portrayed as controlling while he will come across to a US audience as being weak," said the source.
