Two talented siblings went from busking on street corners to performing for a stadium full of people, thanks to a famous singer who happened to be walking by at the right time.

14-year-old Mya Worley and her 13-year-old brother Ronald Jr. were playing music at an intersection in Charlotte, North Carolina last week when two female pedestrians stopped to listen.

The two women had been leaving a local restaurant when they heard Mya was singing a cover of Corinne Bailey Rae while her brother played keyboard. One of the women said: "We gotta get them to play tomorrow."

The other woman then approached the children's father, Ronald Sr., introduced herself as Cyndi Lauper's manager, and asked if his children would be interested in playing a song with Lauper at the Spectrum Center the following day. Not only that, the manager wanted the Worley kids to sing "Girls Just Wanna Have Fun" – which is one of Lauper's most popular songs.

"I saw this little lady also standing there — she was kind of in disguise, almost — but actually I saw her face, and I realized that it was Cyndi Lauper," Ronald Sr. told the Charlotte Observer. "She really didn't want anybody to know that it was her, so she gave me a ‘shh' and put a finger over her mouth."

The kids excitedly agreed, and the very next day, they were welcomed backstage before the show. The Worleys got to have dinner with the backing band; Mya got to rehearse with Lauper; and when the show finally got started, they got to watch the show from VIP seats.

When it came time for Mya and Ronald Jr. to perform, Lauper introduced the youngsters to the audience and told the crowd about how she found them on the sidewalk. Then, when she noticed that Mya was looking a little nervous, the pop star turned to face her new friend and said: "Hell's bells, girl. You've got so much beauty in your voice."

"Take a deep breath … You look like Miles [Davis]. Miles used to turn his back [to the audience when he performed.] But you don't have to. Go ahead."

Mya then kicked off the 80s pop hit with her brother on keys – and her stunning voice blew away the audience. After finishing the first chorus, the full band exploded into the upbeat dance tune that everyone knows and loves.

Judging by the kids' faces during the song, it's probably pretty safe to say that Lauper has earned two more fans for life. Additionally, the once-in-a-lifetime experience thrilled their father.

"I'm an ‘80s child," Ronald Sr. told the Observer. "I grew up listening to her music. I always loved Cyndi Lauper. … So this was just incredible. I tell you, it was so incredible. … Cyndi wrote some things down on paper for us, so I have a piece of paper with her handwriting on it that we'll never, ever, ever, ever, ever, ever lose."
