National Anthem Information

Demi Lovato has risen to fame and become one of the most popular pop stars on the charts, but the Grammy-nominated artist has never performed at the Super Bowl before.

That changes Sunday, when she will sing this year's national anthem at the big game. She'll follow in the footsteps of Gladys Knight, Pink and Lady Gaga, all of whom have sang the anthem at the Super Bowl in recent years.

Although Lovato has never performed on this big of a stage, she has sung the national anthem at other major sporting events, including the World Series and the boxing match between Floyd Mayweather and Conor McGregor in 2017.

In addition to being nominated for two Grammys, she has recorded six studio albums. Her most recent, "Tell Me You Love Me," was released in 2017 and was her first to go platinum.

Lovato's fame started when she appeared in Disney Channel's Camp Rock as a teenager. She has also appeared in various other films and television shows, most of which have been tied to Disney Channel.

While some people will be sitting back and enjoying Lovato's performance and getting ready for the Super Bowl to begin, others will be waiting to see if their prop bets related to the anthem will earn them some big winnings before the game even starts.

As with most aspects of the Super Bowl, there are prop bets to make about the anthem performance. The most popular one will be its length, with the over/under line set at two minutes, according to Bovada.

Last year, Knight performed the national anthem in 2:01. That was the sixth time in the last 11 years that the pregame anthem lasted longer than two minutes, according to FanDuel. The shortest during that span was Kelly Clarkson's 1:34 version in 2012, while the longest was Alicia Keys' 2:35 performance in 2013.

Other prop bets include whether Lovato will wear a skirt, dress or gown, whether she'll forget or omit a word, whether her microphone will be on a stand and what color it will be, all of which are available on Bovada.
