The Scottish singer, 48, will fly to Los Angeles for an appearance on the hit show early next week, her rep tells PEOPLE. "She's excited and happy," says her brother, John Boyle. "She loves America and loves the people. She appreciates their honesty."
Boyle, who made a previous U.S. appearance on America's Got Talent last September, will likely sing material from her upcoming CD, I Dreamed A Dream, due out Nov. 24.
And she is beginning – on a modest scale – to enjoy the fruits of her recent labors: Boyle bought a three-piece sofa and recliner set in burgundy leather for her small home in Blackburn, Scotland, and a new refrigerator. "Moneywise, she's very frugal," says her brother.
He adds, "She wasn't happy staying in London full-time. She can walk around in Blackburn. Just say, 'Hi' and 'How's it going?'to the locals."
