Susan Boyle showed off her trademark hip-shaking shimmy on US television, but hinted it could be the last time fans would see it.
The Scottish sensation demonstrated her famous "wiggle", which she first revealed to Britain's Got Talent judges Simon Cowell, Amanda Holden and Piers Morgan at her initial audition, on the Oprah Winfrey show.
"That's it, that's the last time you see it - that's the Boyle wiggle," she told host Oprah.
Wearing a plum-coloured gown, Susan revealed she was "doing OK" after her stint in rehab last year.
"I hadn't eaten for about a week. I hadn't slept. The feeling was one of extreme exhaustion, but it's a chapter of my life that's over with now," she said.
The 48-year-old, who performed Who I Was Born To Be live with a choir, thanked her late mother for giving her the perseverance to succeed.
"I do feel there's a lingering presence, and that person is my mother. She would have been really proud," she added.
