However, sources say that the 'Toxic' singer had some nip and tuck done during her stay there, reports the Daily Mail.
Meanwhile, it has emerged that two Beverly Hills psychologists are treating the troubled pop star.
Her mother Lynne Spears, who recently reconciled with her daughter, hired professionals to counsel her because she fears Britney is on the brink of a total breakdown.
"They are trying to help Britney work through her issues, which seem to be growing by the day," a friend of the star told the Chicago Sun-Times.
Britney has reportedly already had three long sessions with the team since last Thursday.
