Kate Hudson claims she ''can't afford'' designer clothes.

The 'Bride Wars' actress - who has nine-year-old son Ryder with ex-husband Chris Robinson, and two-year-old son Bingham with fiance Matt Bellamy - insists she has to borrow the high-end gowns she wears for the red carpet because they are too pricey for her budget.

She told the December issue of Harper's Bazaar magazine: ''People think we own all these dresses. But we borrow them! I can't afford to buy that stuff. There are certain things I splurge on, but it's very rare, especially when you have two kids and school tuition.

''I'm not a big high-end fashion shopper. I wish I could but the truth is things are just so expensive. Before Isabel Marant was a million dollars and famous, I used to go to her store in Paris and go crazy, it was so affordable.''

The 34-year-old beauty - who is worth a reported $38 million - credits her mother, Goldie Hawn, with her frugal ways.

She said: ''My mom wasn't a big shopper for us. I think they wanted to instill that in us even though we grew up in a really privileged and lucky lifestyle.''
