The excitement for Ariana Grande's Concert on the Plaza on NBC's TODAY SHOW has been mounting all week. In anticipation of the event, The Today Show picked two pairs of fans out of the crowd to compete in a sing-off to win VIP passes to Ariana's concert tomorrow. However, as the contestants started singing, Ariana's voice came through the speakers and the Broadway baby emerged from the studio. Take a look at the video.

Grande's magnetic charm, impressive voice, and astounding presence have enchanted millions of fans worldwide. Her first full-length album for Republic Records, "Yours Truly" debuted at #1 on the Billboard Top 200, Billboard Digital Albums chart, and iTunes Overall Albums chart.

It yielded one of 2013's most defining songs, "The Way" featuring Mac Miller, which went double-platinum. Shortly after, she was named "Best New Artist" at the 2013 American Music Awards. The first single from her sophomore album, "Problem" featuring Iggy Azalea, saw her become the youngest woman to debut with over 400K sold in the first-week.

In addition to ranking as the 4th highest digital song debut for a female artist and 8th highest ever, the platinum smash debuted at #1 in 65 countries, topping the iTunes overall Top Songs and Pop Songs charts for four weeks. Recent accolades include the 2014 People's Choice Award for Favorite Breakout Artist, Choice Female Artist and Choice Single ("Problem"), the Young Influencer Award at the iHeartRadio Music Awards and the Radio Disney Chart Topper award.
