Whitney Houston in Rehab for Drug and Alcohol Treatment
The singer, 47, who has struggled with substance abuse in the past, has recently entered an out-patient treatment program.
"Whitney Houston is currently in an out-patient rehab program for drug and alcohol treatment," her rep tells PEOPLE in a statement. "Whitney voluntarily entered the program to support her long-standing recovery process."
Houston initially entered rehab in 2004, telling ABC News interviewer Diane Sawyer at the time: "I partied a lot. Trust me: I partied my tail off." But, the singer also admitted, "You get to a point where you know the party's over."
She then received treatment again in 2005, this time with the help of her mother, Cissy Houston.
TMZ.com first reported that Houston was in rehab.
