Jessica Simpson relies on mom to attend fashion meetings

Jessica Simpson relies on her family to ensure the success of her fashion venture - she sends her creative director mom to represent her at meetings.

The star has built up a business empire with her shoe, handbag, denim, swimwear and fragrance lines, and retail sales of her products boomed in 2010 - with experts estimating her business will soon have a $1 billion turnover.

But Simpson admits her lucrative lines aren't all down to her - she has appointed her mother Tina Ann as creative director and relies on the matriarch to make all the important meetings she's too busy to attend.

She says, "I absolutely could not do this without my mom. I appointed her as creative director and we definitely do it together. I'm in most of the meetings but if I'm off doing my music stuff I can always count on my mom to be in every approval meeting and make sure that everything is cohesive and brand-appropriate. I couldn't do it without her."
