Luke Bryan, "country's next poster boy," on co-hosting ACM Awards

Luke Bryan will be co-hosting the ACM awards Sunday night.

(CBS News) Luke Bryan has been called "country's next poster boy" and a "superstar in the making," and since hitting Nashville in 2007 he's had three mega-hit albums with another on its way.

Bryan is a four-time nominee at Sunday night's Academy of Country Music Awards, where he'll debut his new single, "Crash My Party," and if that's not enough, he'll be co-hosting the show with Blake Shelton.

This will be the first time he's hosted an awards show, and the country music sensation told "CBS This Morning: Saturday" host Anthony Mason that he's a little nervous.

"Of course I am going to be nervous, but I will always be nervous, but I think that's the lure and why I got into show business. That challenge, it's the equivalent to a quarterback in his first Super Bowl," he said. "So, yeah, the nerves and the excitement, that is why to you strive to be better in show business."

This is a big year of firsts for the singer. This is also his first year to headline a tour, and he's had a lot of sell-out crowds.

"It's been amazing. It's been an amazing year. I've been really blessed in this business to where each year trumps the other," said Bryan.

With Sunday night approaching, the country star has a lot on his mind. He has to worry about hosting, debuting his new song and being up for four awards, but he's most concerned about his music.

"I have always - and don't take this the wrong way, the hosting is an amazing thing - but when it comes down to showcasing your music for fans, what got you here is music. I don't think anything could be more exciting or- and I am performing a song with Blake, so that's exciting."

Bryan can be seen co-hosting the Academy of Country Music Awards Sunday night at 8 ET on CBS.
