Pop diva Whitney Houston checked into an undisclosed rehab center Wednesday, her second such treatment in just over a year.
"I can confirm she has re-entered a facility for rehabilitation," says rep Nancy Seltzer, confirming an Access Hollywood report.
No other details were released.
In March, 2004, Houston, 40, entered rehab but checked out just five days later. At the time, her spiritual adviser said Houston was battling a prescription drug problem.
In a 2002 interview with ABC's Diane Sawyer, Houston admitted she had used alcohol, marijuana, cocaine and prescription pills during her career.
Last month, Houston became ill on a flight to Paris and was rushed to a hospital there for treatment of apparent food poisoning.
