Susan Boyle, the singer who shot to worldwide fame after appearing on ‘Britain’s Got Talent,’ is gearing up for a Las Vegas residency and is only demanding one thing in her dressing room - Barry’s Tea!

The Scottish singer is following in the footsteps of other megastars like Celine Dion, Elton John and Cher by signing on for a stint in Las Vegas, but has noticeably not taken on their diva-like demands.

One source said, “Susan loves Barry Tea, which is an Irish tea that’s also really popular in Scotland. She doesn’t like American tea, so she brings her own supply of tea bags.”

“Las Vegas is one of the ultimate spots for a performer to play and a residency is a huge deal, but then Susan is a big star who’s sold more than 19 million albums," a source told British newspaper The Mirror.

The upcoming shows in Las Vegas won’t be Boyle’s first time in Sin City - last year, she performed alongside her idol Donny Osmond.
