The troubled singer, who has struggled with drugs and alcohol on and off for years, has been trying to reboot her once-soaring musical career for much of the past decade. The latest attempt came in 2009 with I Look to You. The album and a subsequent tour, however, failed to catch fire, with negative reviews for overseas shows, where fans complained about Houston's voice and performances.
Houston, 47, entered rehab in 2004 and again in 2005 and has admitted to substance abuse problems, but said around the time of her 2009 album release that she was feeling stronger and was focused on her sobriety.
TMZ reported that Houston checked into the program 10 days ago. She has been mostly out of the public eye lately, but did sing onstage with Chaka Khan at a Prince concert in Los Angeles last week.
According to a USA Today report, Angela Bassett, Houston's co-star in the 1995 hit film "Waiting to Exhale," said a sequel is in the works and that the entire original cast — presumably including Houston — is expected to appear in the film version of author Terry McMillan's 2010 follow-up novel, "Getting to Happy." Actor Forest Whitaker is reportedly slated to direct the film from a script by McMillan.
