Simon Cowell is reportedly "delighted" that Susan Boyle has decided to make a comeback.

The 57-year-old Scottish singer will compete in an all-star, global version of the show that originally made her a celebrity.

The chanteuse made an impression across the world when she auditioned for Britain's Got Talent in 2009. Boyle stunned the nation with her incredible rendition of "I Dreamed a Dream" from the Les Miserables soundtrack.

According to Heart Radio, the upcoming TV all-star special will see Boyle perform in front of Simon Cowell and judges Heidi Klum, Mel B, and Howie Mandel. Other notable contestants from over the years will also be involved,

A source from Cowell's production company told The Sun, "Simon was delighted Susan decided to come back" for "America's Got Talent: The Champions."

In the almost-decade since her debut, Boyle, whose parents are Irish, has sold over 25 million records. However, she has largely shunned the public eye in recent years.

In 2017 she told the media that she had been targeted by a gang of teenagers who were continuously tormenting and verbally harassing her at her home in Blackburn.

"They have been shouting at me, taunting, saying vile things, swearing. And on one occasion they were throwing things at the bus I was sitting on," she told the Daily Mail.

"I love my house, it's where I grew up. Why would I move out because of a group of teenagers who behave like that? They are bullies who shout and throw things, but it is my home and where I feel safe."
