Whitney Houston, who recently checked herself into drug rehab, was on the minds of many attendees at the Soul Train Awards, from Usher, who told ‘Extra’, “She’ll be fine,” to ‘American Idol’ champ Ruben Studdard, who admitted, “She’s always been a superstar in my heart. I’m a big fan, and I hope she gets better.”

People magazine’s Peter Castro tells ‘Extra’ that Whitney Houston’s mother will likely take care of her 10-year-old daughter Bobbi Kristina. “Cissy Houston, her mother, is always there for her and she’ll probably take over caring for Bobbi Kristina now,” Castro revealed. People also reports that, according to a fan, Houston was so disoriented at her 40th birthday party that the star had a hard time taking off her jacket.

Sources confirmed to Billboard that most of the Arista Records 170 staffers will be let go as the label folds into BMG’s sister divisions. The downsized label would retain a small A&R and marketing staff but be placed under the RCA Music Group banner. It’s widely thought that the LaFace-affiliated acts, including OutKast, Usher, Pink, and Cee-Lo will be transferred to Jive. while Sarah McLachlan, Dido and Avril Lavigne would shift to RCA, and Whitney Houston, Kenny G and rap newcomer J-Kwon would go to J Records.

People magazine Assistant Managing Editor Peter Castro tells ‘Extra’ something dramatic must have happened for Whitney Houston to finally check herself into a drug rehab facility. “The world has been waiting for this for a very long time,” Castro said. Meanwhile, they’ve learned Houston has laid off some of her management people, since she will be out of action “indefinitely.”

A source close to Whitney Houston tells The Chicago Sun-Times that the bizarre claim of a pregnancy — attributed to Houston by several Russian media outlets — alerted those close to her “that she was in serious trouble. Again.” Though Houston’s spokeswoman immediately denied the pregnancy story, once the entertainer returned home, several friends and family members “started watching Whitney even more closely than they have been,” said the source. A surprise intervention by a half-dozen members of Houston’s inner circle over this past weekend convinced Houston to enter an unnamed drug rehabilitation program early Monday.
