Sarah Harding planning solo career

London: Former Girls Aloud star Sarah Harding is working on her first solo project. The 30-year-old singer, who checked into rehab last year to address a sleeping pill addiction, has been pursuing a career in films but she is preparing to return to her music roots in 2013, reported Contactmusic. "There`s quite a lot going on this year, but it`s in the pipeline right now, so I can`t really say much about that! Next year I am preparing for solo material, so watch this space," Harding said. The singer-actress has recently finished filming ‘Run For Your Wife’ in which she plays one of the wives of the lead character, John Smith. The film is scheduled for release this year. PTI
