BRITNEY SPEARS - SPEARS IN AND OUT OF REHAB

Pop star BRITNEY SPEARS checked herself into a rehab facility in Antigua, but abruptly left after only one day of treatment. The TOXIC singer has been criticised for her constant partying since filing for divorce from KEVIN FEDERLINE in November (06). According to American publication People, the 25-year-old checked herself into rocker ERIC CLAPTON's Crossroads Centre Wednesday (14FEB07), but then checked out less than 24 hours later. On Tuesday (13FEB07), Spears former assistant FELICIA CULOTTA, wrote a letter that was posted on Hollywood.com's The Other Blog, stating that Spears' friends and family were trying to get her to seek professional help, without much success. She wrote, "There's just so much you can do to help a person. I cannot convince her in any way to love herself. "I cannot save her from herself, nor can I commit her to any type of treatment program against her wishes and will. "I am throwing my hands up and realising that I am helpless over another."
