Victoria Beckham sends emails on the toilet.

The former Spice Girls singer insists her life isn't particularly "glamorous" and her husband David Beckham is constantly urging her to stop working on her fashion empire when they're at home together.

She said: "If you dream big and work hard, you can achieve great things.

"I learnt an enormous amount being very young and very, very famous - having everything one minute and then losing it just as quickly.

"You realise it's much more difficult to maintain success than it is to actually achieve it - and it's not as glamorous as people would think.

"Quite often at the weekend, I'll end up hiding in the toilet sending emails because David is like, 'Put that phone down'. "

The 43-year-old designer - who has children Brooklyn, 18, Romeo, 14, Cruz, 12 and six-year-old Harper with David - moved into fashion in 2008 and she's only just realised how much of a "brave" move it was to start a new career away from her pop star image.

She said: "Looking back, I don't think I realised how brave I was to get into this.

"I always loved fashion, even in the Spice Girls days, but if I had known then what I know now, I would have been much more frightened about the whole thing."

But Victoria recently admitted she poured everything into achieving her fashion "vision".

She recalled: "I really put everything into this; it was a new career for me and I had a vision. I surrounded myself with the right people, which, when I started was just two people - one girl working with me on the design and another on the production. It was very different from what other people had done; I wasn't a celebrity with a licensing deal.

"It was all about being focused, honest, and doing it in an incredibly humble way."
