According to the spokesman, no emergency papers will be filed as had been planned in the custody matter.
TMZ.com first reported that Spears had gone back to rehab.
On Tuesday, Spears, 25, entered the Promises rehab facility in Malibu, only to check out the following day.
Leaving the clinic “was against their advice,” a source told PEOPLE Wednesday.
Before entering rehab, Spears had a wild weekend of alarming behavior â€“ capped by the night she shaved her head.
Last week, the singer also visited Eric Clapton’s Crossroads Centre in Antigua but left after just one day and headed to Florida, a source told PEOPLE on Friday.
“She spent a fair amount of time there, about two hours,” says a local source. “She walked around and checked it out.”
