Now its no secret that the legendary singer/actress Whitney Houston has had an ongoing battled with drugs & alcohol over the past years. Well today it has been reported that Whitney has re-entered rehab according to her publicist.

The voluntary measure is part of Houston’s “long-standing” recovery process, says publicist Kristen Foster. She previously visited a rehab facility in 2005 for unspecified reasons.

The big-voiced diva is getting ready to film the sequel to 1995’s blockbuster Waiting to Exhale. While the original cast including Angela Bassett and director Forest Whitaker have signed on to shoot the movie, no word if this recent stint will affect the filming schedule.

Houston is still allowed to go out in public, though she’ll need a monitor at all times, according to TMZ. She recently performed with Prince and Chaka Khan at the former’s show in Los Angeles.
