The performers for the 2014 Arthur Ashe Kids' Day have plugged in and are ready to go.
After going through rehearsals on Friday, the talented entertainers from around the globe are set to put on a high-energy concert inside Arthur Ashe Stadium on Saturday. Among the performers are country superstar Hunter Hayes, breakout duo MKTO, girl group McCLAIN, British boy band The Vamps and teen sensation Madison Beer. Outside Arthur Ashe Stadium, the Hess Express Stage features some of the hottest rising acts across the country including Hollywood Ending, Kalin and Myles and Zach Matari.
Headlining the stadium show this year is Grammy nominee and country superstar Hayes, whose has sold more than 1.1 million copies of his self-titled debut album released in 2011. His second single off that album, "Wanted," sold 3.5 million copies and reached the top of the Billboard Hot Country Songs charts.
Hayes is currently promoting his sophomore album "Storyline," which was released this May.
"This is gonna be awesome. It's a really cool setup because we get a birds-eye view of the action from where we are on the stage," said Hayes. "Music was my discovery when I was young and that's been my life since then, so I support anything that involves giving young adults the chance to find something that they feel passionate about. It's a special day to be part of."
Hayes said he was flattered by the invitation to perform at this year because of the impressive list of Kids' Day alumni, including Britney Spears, Rihanna and Justin Bieber.
"It's a big deal," he said. "There's a long list of incredible entertainers and performers who have been a part of this, so to see my name on that list is pretty sweet."
Joining Hayes in the stadium show is Beer, a protege of Canadian crooner Justin Bieber. She began posting videos of herself singing covers of popular songs in early 2012, when she was just 12 years old. Her cover of "At Last" by Etta James eventually attracted the attention of Bieber, who immediately took her under his wing.
"He tweeted that video out to his millions of fans, which was crazy and surreal," she said. "He got in contact and I'm out in California now. I'm in the studio a lot, making lots of music and doing what I love. I couldn't be happier."
It's likely that she got some tips from Bieber about how to rock the crowd at Arthur Ashe Stadium, since his 2009 performance helped propel him to worldwide superstardom.
"He's given me a lot of advice," said Beer. "He's just told me to always keep your head up and keep your eye on the target. It's the same advice I'd give to people trying to make it in music. Just follow your dreams and never give up. I never gave up and now I'm doing what I love every day."
The stadium show takes place from 1 to 3 p.m. ET on Saturday. CBS Sports will broadcast the event on Sunday, Aug. 24, from noon to 1:30 p.m. ET.
