Houston, we have a problem.

Multiplatinum singer Whitney Houston has entered an out-patient treatment program, her rep confirms to Us Weekly.

"Whitney Houston is currently in an out-patient rehab program for drug and alcohol treatment," her rep tells Us in a statement. "Whitney voluntarily entered the program to support her long-standing recovery process."

The "I Will Always Love You" singer has been open about her drug use in the past, telling Diane Sawyer in a 2002 Primetime interview that she had "at times" used marijuana, cocaine and pills to get high.
