After wrapping up a successful concert tour, you'd think Reba McEntire would want to take some time off to relax.

Instead, the tireless country star has been preparing for her 10th turn as host of the Academy of Country Music Awards today in Las Vegas. Over the years, she says she's become more at ease hosting the event.

"I've got a lot more confidence," McEntire said at rehearsals Friday. "I know a lot more of these folks that I get to work with, and we're a wonderful team. And it's, I don't want to say, 'old hat,' 'cause I still get a little nervous and butterflies still happen when I get on that stage. But I think I have more fun with it now than I did the first time."

The 43rd annual Academy of Country Music Awards airs live at 6 p.m. MST tonight on CBS.
