Growing up in LA, Nicole is the daughter to iconic soul singer Lionel Richie. While making her rise in the Hollywood scene alongside the Hilton sisters, Nicole unfortunately fell through some dangerous pitfalls. The hard partying Simple Life star battled the constant media scrutiny on her weight and even had a DUI back in 2006.

Nicole quickly rebounded and found herself in love with her now husband Good Charlotte lead singer Joel Madden. The two welcomed their daughter Harlow Winter Kate Richie-Madden in 2008 and son Sparrow James Midnight Richie-Madden in 2009.

Between balancing motherhood and two fashion lines, Nicole has also published a book The Truth About Diamonds in 2005 and she’s had several guest spots in TV shows such as Chuck and 8 Simple Rules.

Nicole will make a return to reality TV in NBC’s Fashion Star. The fashionista will be a mentor alongside fellow reality alum turned designer Jessica Simpson and menswear designer John Varvatos.
