Nicole Richie in rehab?

Nicole Richie's publicist is denying reports that the Simple Life star has entered a rehab facility for anorexia and drug use.

"She is not in rehab. She is at home in Glendale. Sobriety is an ongoing process but she is sober," the rep told Usmagazine.com.

Celebrity blogger Perez Hilton is claiming reliable sources have confirmed Richie checked into rehab on May 11 and is now receiving outpatient care at home.

Richie's weight and substance problems have been making headlines for years. Most recently, she was arrested in December for a DUI, allegedly mixing Vicodin with marijuana and then driving the wrong way down a highway. She is due in court June 8 for the hearing.
