Pop singer Britney Spears has checked herself out of rehab again after spending just 24 hours in the treatment facility.
According to US reports, the 25-year-old singer left Malibu rehab clinic Promises yesterday, just a day into her treatment programme.
A source told People magazine that the singer had checked out of rehab against the advice of staff there.
The source said: "It was against their advice. If she comes back for treatment, Promises will have to assess the situation. Sometimes people come back but it doesn't look good."
This is the second time in the space of a week that Spears reportedly checked into a rehab facility and left after a day.
Last week the singer sparked concern for her well-being after she shaved off all her hair.
