Last night during what proved to be the last game of the World Series, the X Factor's Demi Lovato belted out the national anthem!
To open game 4, she sang "The Star Spangled Banner" before the Detroit Tigers lost to the San Francisco Giants. Before taking the field, she Tweeted, "So excited to sing the National Anthem at game 4 of the World Series tonight!!!!!"
Wearing black leggings, a black graphic tee with a blazer and high heel boots, Demi showed why she has the chops to sing in front of such a huge audience.
And she's not alone -- previous singers during this World Series run include American Idol's Phillip Phillips, Matthew Morrison from Glee and Zooey Desachanel from New Girl.
Although fans in the stadium cheered, online viewers weren't so supportive with their comments. Take a listen below and let us know what you think!
