Reba McEntire has been preparing to perform the National Anthem at Sunday’s (February 11th) Super Bowl. The first thought that she had when she found out she was going to do this was to decide what to wear. She got hooked up with one of her favorite designers, Ralph Lauren, who she’s never met before.

“Well, for us to get ready to sing the National Anthem, of course we had to find out what I was going to wear,” she says. “So, (prominent fashion designer) Cristina Ehrlich, oh man, she hooked us up with Ralph Lauren to make my outfit for me to sing the National Anthem at the Super Bowl. I have never met Ralph Lauren, and I am so excited because I’ve been a huge fan of him for many, many years and that I’m gonna get to wear a Ralph Lauren outfit, it’s oh, just so exciting. Then Adam Blackstone put the music together for me and we were gonna do it acapella, but Adam said, no, it might be better with the band, so we have that ready to go, and now, it’s just let’s get there and start singing.”

The Country Music Hall of Famer also had a little help from her boyfriend, actor Rex Linn, on getting ready for the Big Game and told the press earlier on Thursday (February 8th) some of her tips on being prepared to perform on such a huge stage. “I prepare by being prepared. I’ve been singing the National Anthem in the shower, when we get in the car,” says Reba. “Rex, my boyfriend, is a huge football fan, played all sports when he was going to school, and he’ll say, ‘Ok, sing it one more time.’ I said, ‘I think I know the words real good right now, so I’m alright.’ But just to be prepared and know that everybody’s gonna be singing it with me, that helps. If I know if they’re singing along and they’re remembering and having fun too, that’s easier on me, but just to be prepared when you walk out there.”

The global superstar explains how honored she is to perform the National Anthem on Sunday. “I am honored beyond words to be chosen to get to sing it,” she says. “It means that I get to sing a very special song for all Americans, people all around the world, who have really worked so hard for our freedom and to give us peace, and it’s not about me. I’m the representation of this song, and I’m just honored to get to sing it. It’s a good one. I’ve been doing it for 50 years, and I’m really proud to get to sing it.”
