Demi Lovato will perform the national anthem at Game 5 of the World Series.

Lovato will belt out the anthem on Monday.

The Texas Rangers and the St. Louis Cardinals are tied 1-1 in the seven-game series.

Lovato got a boost from her big sister Dallas, who tweeted during Game 1 that her younger sister should sing the national anthem during the Major League Baseball championship series.

Game 3 airs Saturday and all games are being broadcast on Fox.

Lovato, the former star of the Disney Channel’s “Sonny With a Chance,” released her third album “Unbroken” last month.
