Stella Mccartney won't have any more children.

The fashion designer already has four kids - Miller, seven, Bailey, six, Becket, five, and two-year-old Reiley - with husband Alasdhair Willis and while she loves being a mother, she has no desire to add to her already large brood.

When asked if she will have any more, Stella said: ''No. If it ain't broke, why fix it?''

Stella admits being a working mother is hard but says her family will always come before her career, although would never let her business fail.

She said: ''My family always comes first. But this (House of Stella) is my second family. When I'm with my husband and kids, one of my ears is listening out for my work family. And it's the other way around when I'm here.''

The 41-year-old sartorialist gets a huge buzz from her work and loves it when her collections get good reviews.

She told Britain's ELLE magazine: ''We all love it when a show is well received. We love it when we see somebody wearing it. We feel the reward of the work and I think that drives you, helps you do it and get your sleeves rolled up because you see that there's a validity to what you're doing and people are responding to it in the way you want. That's very satisfying.''
