While celebs like Jennifer Lopez, Jessica Simpson and Gwen Stefani have their own clothing lines to worry about, Reese Witherspoon has found a slightly more relaxing option.

Glamourmagazine.co.uk reports that the Oscar-winning actress has been offering her advice to good friend and Nina Ricci Artistic Director, Olivier Theyskens. Theyskens says, "My best friend Reese has helped me design [the latest collection] -- she is always giving me materials and advising me." The recently divorced mom of two has been wearing Nina Ricci shoes on the red carpet, an insider tells Glamour, continuing, "Olivier and Reese herself love the combination of the brand and her style."
