Demi Lovato will perform "The Star-Spangled Banner" before Saturday night's fight between Floyd Mayweather and Conor McGregor in Las Vegas.
The New York Daily News notes that Lovato last sang the national anthem at a high-profile sports event in 2015, when she performed it at Citi Field during Game 4 of the 2015 World Series.
Other A-listers who have performed the national anthem at Mayweather's fights include Jamie Foxx, Monica, Tyrese Gibson, and Wyclef Jean.
There has been no announcement as to who might perform Ireland's national anthem for McGregor.
