Socialite Nicole Richie hit back at claims she is in rehab fighting anorexia and a lethal addiction to painkillers, insisting she is enjoying life at home. Speculation that Richie the adopted daughter of singing legend Lionel Richie had entered the Beau Monde facility in Laguna Beach seeking treatment for an eating disorder and substance abuse surfaced last week. But a spokesman for Nicole denies the claims, saying she is in fact at home in Glendale, California. The representative tells Tmz.com Richie recently visited her therapist, but her recovery is "an ongoing process" and she is "completely sober."
