Whitney Houston has voluntarily checked herself into an out-patient program to be treated for drugs and alcohol, according to people.com. The 47-year-old singer has had a longtime battle with substance abuse, but has reportedly been sober for the last few years.
According to a statement from her rep, Whitney went back to rehab to "support her long-standing recovery process." The rep also clarified that she is not currently admitted but in an out-patient rehab program for drug and alcohol treatment.
Whitney first went into rehab back in 2004 telling ABC's Diane Sawyer that "You get to a point where you know the party's over."
