Jamie Foxx performing the national anthem at the Floyd Mayweather Jr vs Manny Pacquiao fight on Saturday night.

"That night my inner ears pack falls off just before I'm supposed to sing," Foxx told ET. "So I had to try to listen to the organ through the speakers of the stadium and try to catch what it is."

Following Foxx's performance, Twitter quickly blew up with criticism of the 47-year-old actor/singer.

But Foxx said that inside the arena "you would have thought I was getting a standing ovation."

"Then…somebody told me about the internet [backlash] and said, 'Oh, people are clowning you.' When I listened I said, 'Oh yeah, we're off.'"

It sounds like Foxx is looking forward to redeeming himself.

"I wanted that to be the best moment and, unfortunately, it didn't go 100% like we wanted," he said. "But we'll get another crack at it."
