I seriously can't keep up with this girl any longer, Anyways, People reports that Britney Spears had already left Promises, a residential rehab facility in Malibu after being there for a day.
"It was against their advice," says the source. "If she comes back for treatment, Promises will have to assess the situation. Sometimes people come back, but it doesn't look good."
Promises is not a locked-down facility, so a patient is able to leave the program if he or she wants to.
