NEW YORK – A year after her first reported stay in rehab, Whitney Houston (search) has again checked into a rehabilitation facility.
"Whitney Houston has re-entered a rehabilitation facility today," her publicist, Nancy Seltzer, told The Associated Press Wednesday. She declined to provide details.
The news was first reported by syndicated entertainment TV show "Access Hollywood" (search).
In March 2004, Houston checked herself into an undisclosed rehabilitation center.
After years of denying drug use, the pop diva said she had used cocaine, marijuana and pills in an interview with Diane Sawyer on ABC's "Primetime" in 2002.
She has said she was using the power of prayer to help her get over drugs.
In January 2000, Houston left behind a bag at an airport in Hawaii that allegedly held less than half an ounce of marijuana and three partially smoked marijuana cigarettes; a petty misdemeanor drug charge was dismissed when a counselor said Houston didn't need treatment for substance abuse.
Houston, 41, has been working with producer Clive Davis on a comeback album.
The Grammy-winning singer is known for her rendition of "I Will Always Love You" and her role in the 1992 film "The Bodyguard." Houston and R&B singer Bobby Brown (search) have been married since 1992 and have an 12-year-old daughter, Bobbi Kristina.
Brown has a history of drug and alcohol arrests.
The couple live near Alpharetta, a suburb north of Atlanta.
