Victoria Beckham today admitted she is a "control freak in a nice way" and admitted: "Everyone thinks I'm going to be such a cow."
Speaking at Vogue Festival in central London, the pop star-turned-fashion guru discussed the challenges of juggling her booming business and being a mother-of-four.
The 39-year-old made an auditorium packed with aspiring fashionistas laugh when she joked: "Everyone thinks I'm going to be such a cow - I get it because I think the same when I see the pictures."
"I'm a perfectionist, I like everything to be right. I'm probably a complete pain in the neck to work with because it is really important to me because I've grown this brand from nothing to where it is now," she added.
Accompanied by her eldest son and budding model Brooklyn Beckham, Posh Spice said she "constantly feels guilty" as a working mum.
The designer and entrepreneur said: "I think you feel so torn, don't you? But I've got great people who handle my schedule and everything does revolve around the children.
"So, if there's a parents' night or an Easter bonnet parade or a nativity play, whatever it might be, then I plan everything around that so I can always be there."
She also confessed that being a mother also means she does not get enough sleep, saying: "I'm up early in the morning with the kids, getting the kids ready for school, going through the times tables tests and spelling tests and all that kind of thing, which I'm sure every mum is used to doing early in the morning.
"But then I'm also up quite late at night because I have a baby and then I have a 14-year-old who refuses to go to bed... Brooklyn."
Answering questions from the audience, she said her mother Jacqueline has been her role model.
"My mum loved fashion, was always very glamorous and has been married to my dad for a million years and looking after three children, and that's really inspiring," she said.
She told how she is enjoying life back in London since returning from the US, even though husband David is in France playing for Paris-St Germain.
"Living in London is very, very different from Los Angeles, but it's great, it's inspiring, London is such an inspiring place to live, so multicultural, it's interesting, I'm happy," she added.
