Dr. Phil McGraw – who met Britney Spears at Cedars-Sinai hospital Saturday – will devote his Monday taping to the pop star's problems. The show will air Tuesday.
The syndicated talk-show host and therapist says he talked to Spears as she was leaving the facility, where she was held on a mental lockdown
after a custody dispute. She was released after just a day and a half from a possible 72-hour stay.
In a statement to Entertainment Tonight,
McGraw said: "My meeting with Britney and some family members this morning in her room at Cedars leaves me convinced more than ever that she is in dire need of both medical and psychological intervention.
"She was released moments before my arrival and was packing when I entered the room. We visited for about an hour before I walked with her to her car."
Still, a source tells PEOPLE that McGraw "talked to both Britney and [father] Jamie about how her being released was one of the worst decisions that could have been made." The source says they packed up within 10 minutes.
McGraw has a history of supporting the Spears family
. In December, after the announcement of 16-year-old Jamie Lynn Spears's pregnancy, he told PEOPLE that "an asset that Britney and Jamie Lynn both have is a great and dedicated mother," Lynne Spears.
"They're a very strong, close-knit family," says Dr. Phil's wife Robin, "They're relying on each other."
