However, she had no regrets.
"I've been to some wonderful places and met some wonderful people," she said.
Some opera singers were born with the "x-factor" - something that cannot be taught, she said.

"There are some people that are born with it," she said.
Dame Malvina gushed about the three boys of Sol3 Mio, calling them "brilliant".
"They are very good entrepreneurs.
"They are really good at looking after each other and they are great at business planning really," she said.
She joked about "telling them off" at times.
"If you tell them off, as I do sometimes, they look at you like they have been really naughty boys," she laughed.
