Susan Boyle delights Oprah Winfrey after erratic U.K. tantrums

THE British singer looked to be back on an even keel when she appeared on the US talk show.

She performed her famous “Boyle wiggle” in front of a delighted Oprah Winfrey on Tuesday, but then said that was the last time she would ever do it.

SuBo had fans and producers worried after behaving erratically last week. Sparking fears she was struggling to cope with her high-pressured career again, she had foul-mouthed tantrums at a cafe near her Scottish home, as well as in Heathrow airport’s VIP lounge on Jan. 12.

But the Britain’s Got Talent star kept it together and took another step toward conquering America when she sang and chatted on the Oprah Winfrey Show.

Boyle, who has learning difficulties, spoke to Oprah about her mother’s death and the difficulties of coping with fame.

“My mum died two years ago,” she said.

“After that there was a wee period where I didn’t sing … You try and keep going through that pain and that’s what I try to do with my singing. I am very slowly getting over it.”

Oprah questioned SuBo about her breakdown last year, when she spent time in rehab center the Priory.

“There are two types of exhaustion, exhaustion due to ill health and exhaustion due to work,” she replied.

“I like to be busy so I was very exhausted because of work. But I was fine. It’s a chapter of my life which is over now.”

After performing Who I Was Born To Be, she had the audience in stitches as she taught Oprah her famous wiggle. Afterwards she vowed, “That’s the last time you will see it. That’s the Boyle Wiggle.”
