Susan Boyle - Susan Boyle's Rehab Confusion

Susan Boyle can't remember her time in a rehab clinic.

The Scottish singer - who shot to fame after appearing on UK TV talent show 'Britain's Got Talent' - was treated at The Priory clinic in London after struggling to cope with the fame and attention the show brought her but admits she struggles to recall what happened at the facility.

She said: "I don't really remember much about it. After the final, I went there with extreme exhaustion. I hadn't slept properly for about a week and I didn't know what was wrong with me.

"II was in there for three days and I've never felt so tired but I look back on it now and it was a necessity. I wanted a rest and a break, without all the cameras."

The 'Wild Horses' singer has undergone a make over since her first appearance on the show and says she feels much more "refined".

She added: "I brush up quite well, it's like a cygnet to a swan. Now I see a sophisticated lady but inside I'm still the same, just a little bit more refined in some ways. The whole process has been good for me."
