As more and more reports of celebrities set to attend Saturday night’s boxing match between Floyd Mayweather and Conor McGregor filter in, others are being scheduled for helping out.

Demi Lovato will sing the national anthem prior to the start of the event, which takes place from the T-Mobile Arena in Las Vegas.

Lovato is a GRAMMY-nominated artist with more than six billion single streams and nine platinum and multi-platinum singles.
