Whitney Houston has entered rehab, according to TMZ. The site's source says she checked herself into a facility about 10 days ago.
"Whitney Houston is currently in an out-patient rehab program for drug and alcohol treatment," Houston's rep tells PEOPLE. "Whitney voluntarily entered the program to support her long-standing recovery process."
Houston, 47, has publicly battled drugs and alcohol in the past, entering rehab both in 2004 and 2005. Recently, Houston's 18-year-old daughter Bobbi Kristina has been caught up in an alleged cocaine scandal of her own.
Houston is allowed to leave her rehab facility with a monitor. "Just last weekend, Houston was enjoying herself at a Prince concert in LA ... with her daughter right by her side," TMZ writes.
A TMZ source adds that Houston's visit to rehab comes as "she's cleansing herself to get ready for a new movie."
