She's notorious for looking miserable when she's photographed, but in a revealing interview Victoria Beckham has given a hint at her insecurities and believes she is only successful because of her work ethic – something she is determined to pass on to her four children.
She told Elle magazine: "When I was on stage with the Spice Girls, I thought people were there to see the other four and not me.
"And when I go out with David and people take pictures I think, 'They're here to take David's picture'."
And because of this feeling of being in the shadows, she has always been driven to succeed through sheer hard work. Now the successful and celebrated fashion designer, said she hopes to pass her work ethic on to her children Brooklyn, 13, Romeo, 10, Cruz, seven, and Harper, one.
She said: "I don't have to work, I need to work. But I have a good work ethic. David has an incredible work ethic.
I want my kids to have a good work ethic. I believe you can achieve anything if you work hard enough to get it.
The former Spice Girl has admitted she is a 'control freak' who finds it hard to trust others...and fears her co-stars and even her husband are more popular than she is.
"You've got to trust people. And because I am a control freak, sometimes that's difficult for me, because I want to micro-manage absolutely everything," said Victoria, 38.
"I can't hand over. But I'm trying to do that more. It's hard because I have such a specific vision."
Last year, Victoria admitted juggling her fashion business with motherhood had left her exhausted. She said: "I'm not going to lie about it, I'm tired. I'm really tired but I'm also very happy with my life.
"I'm basically just like any woman who's working and has lots of children - it's tough. "I'm not getting much sleep at all. Harper's not sleeping that great, and I've been taking Skype business calls throughout the night too because of the collections."
