Demi Lovato "doesn't remember anything" from her performance at the Super Bowl on Sunday.

The 27-year-old belted out The Star-Spangled Banner ahead of the game at Miami's Hard Rock Stadium in Florida, but speaking to Entertainment Tonight after the event she confessed she "blacked out" during the song.

"I don't remember anything! I blacked out," she gushed. "I was so excited."

Lovato also reacted to a tweet she posted a decade ago, manifesting her dream of one day singing at an NFL (National Football League) Championship Game, writing: "Dreams really do come true y'all."

The star's performance was met with controversy, after Beyonce and JAY-Z hit headlines for deciding to stay seated while she performed the song, in an apparent statement echoing the protests of star athletes such as Colin Kaepernick, who famously "took a knee" during the anthem as a protest against police brutality.

Neither star has yet to comment on the move.

Lovato's performance at the game came one week after she returned to the stage at the Grammys with her emotional new song Anyone, marking her first major performance since her overdose in July, 2018.
