Victoria Beckham "always felt uncomfortable" in the Spice Girls, the band's former manager Simon Fuller has claimed.
The 55-year-old entrepreneur, who worked with the girl group through the peak years of their success, has claimed Victoria only found her "true vocation" when she quit music and started working in the fashion industry.
Simon explained: "Victoria, coming out of the Spice Girls, being married to David Beckham, launched a solo career. She never felt comfortable. Even in the Spice Girls - it was great fun, she was in the world's biggest group for two or three years - but she didn't feel comfortable.
"She could sing pretty well, she could dance pretty well, but she always felt uncomfortable."
Although Victoria went on to enjoy some success as a solo artist, Simon revealed fashion has always been her true "passion".
Speaking at the Business Innovation Awards in Los Angeles, Simon said: "When the Spice Girls broke up, she had a few songs as a solo artist but she wasn't happy and she said to me 'Simon, I just don't want to do music any more. What do you think I should do?'
"It was one of those things that you get this kind of clarity of vision. I've known Victoria since she was 18 and her passion in life was always clothes. She was called Posh Spice because she always wore the best dresses and she knew everything about clothes.
"I said 'You should be in fashion. You should be a designer'."
Simon was named the Entrepreneur of the Year at the seventh annual Business Innovation Awards on account of his success in the music, television, sport and fashion industries.
As well as managing artists like the Spice Girls and Amy Winehouse, he also created 'American Idol' and has been named by TIME magazine as one of their 100 most influential people in the world.
