Socialite and fashion designer Nicole Richie is no stranger to rehab. The former reality star entered rehab in early 2003 after she was arrested for suspicion of possessing heroin. Richie visited rehab again in 2007 for a prescription pill addiction and weight problems. Richie, who is now clean, recently married Joel Madden. The couple have two children together. - Xfinity Entertainment Programmers
