Matthew Perry has revealed he is returning to rehab to "focus on my sobriety".
The former Friends star, who has struggled with prescription pills and alcohol abuse in the past, is choosing to go back to a treatment centre as part of his ongoing recovery.
He told TMZ.com: "I'm making plans to go away for a month to focus on my sobriety and to continue my life in recovery. Please enjoy making fun of me on the World Wide Web."
Matthew, best known for his role as wise-cracking Chandler Bing in the hit TV series, was in rehab twice, in 2001 and 1997, for prescription pill addiction.
A spokesperson for the 41-year-old actor told People: "There was no relapse," and that he plans to enter the facility shortly.
