From 'Simple Life' to rocker's wife.

Former reality star Nicole Richie wed Good Charlotte band leader Joel Madden over the weekend.

Richie's publicist Nicole Perna says in an e-mail to The Associated Press Sunday that the 29-year-old socialite and her longtime boyfriend Madden, 31, were married Saturday in Los Angeles.

The couple, who dated for more than four years, have a 2-year-old daughter, Harlow Winter Kate, and a 15-month-old son, Sparrow Midnight.

Richie won national attention costarring on TV's "The Simple Life" with Paris Hilton and has since been a staple in the tabloids. 

She has recently taken to writing books and designing clothes.
Richie has her own fashion line, Winter Kate, and a shoe and accessories line, House of Harlow.
