Luke Bryan, you've just sang at the Super Bowl! What are you going to do next? 

"I need a drink now!" the country crooner told ET's Kevin Frazier moments after exiting the field at NRG Stadium in Houston on Sunday. "It was crazy!" 

Meanwhile, Bryan's fellow country A-listers took to Twitter to laud his rendition of "The Star-Spangled Banner."

"You KILLED it!!" tweeted Lady Antebellum's Hillary Scott, while Tim McGraw wrote, "Makin' us proud!"
