LATEST: Troubled pop star Britney Spears has reportedly fallen for a rock musician while she is in a rehabilitation facility, according to press reports in the US. The 25-year-old has started dating a musician she met while attending Alcoholics Anonymous (AA) meetings and reportedly plans to move in with him once she's finished her stint in rehab. According to US publication National Enquirer, the TOXIC singer is dating JASON FILYAW, the 33-year-old lead guitarist for the rock band RIVA. A source explains, "Britney adores Jason. He's been a tower of strength for her at the lowest point in her life. "She's convinced Jason can help her through rehab because as an alcoholic, he's been through the same thing." According to the publication, Spears emails and phones Filyaw constantly and they even have pet names for each other - he calls her SUGAR, KITTEN and MY LADY, while she refers to him as MR SECRET UNDERGROUND GUY and J-SUN.
