Whitney Houston is no longer living under the watchful eye of a drug rehab chaperone, reports PEOPLE.

"She successfully completed the 30-day treatment program and she is now in an aftercare program, the specific terms of which are confidential," said Houston's Atlanta attorney, Mark Trigg.

Houston, 40, entered what was reported to have been a one-month program in early March, but after five days checked out of the center (whose location was never disclosed but believed to have been in the Midwest).

"Miss Houston is continuing the prescribed treatment as was planned," her publicist, Nancy Seltzer, told New York's Daily News at the time. "Her movements are in total keeping with the program."

Once she left the center, Houston reportedly moved into a rented residence near her own suburban Atlanta home.

Last week, Houston's husband, R&B singer Bobby Brown, 35, was ordered to stand trial on misdemeanor battery charges that he allegedly hit his wife in the face at their home near Alpharetta, Ga., in December, leaving her with a bruised cheek and a cut inside her lip.

In a recent interview on Dateline NBC, Brown described the domestic incident as a "little spat" while the two were playfully "slap boxing" but that Houston took one of his jabs a "little serious."

At last Wednesday's hearing, Brown and Houston exchanged smiles and left the courtroom arm-in-arm. They made no comment to reporters waiting outside.
