Cheryl Cole visits Harding in rehab

London: Singer Cheryl Cole has visited her Girls Aloud bandmate Sarah Harding in rehab after becoming "really concerned" about her.

Harding checked into an American treatment facility in Arizona earlier this month to receive help for depression and alcohol addiction. "Cheryl is really concerned for her friend Sarah. She made time in her busy schedule to travel over to Arizona and visit her in the rehab centre," femalefirst.co.uk quoted a source as saying. IANS
