Blake Shelton sings about flirting with a girl in his recent No. 1 hit, "Sure Be Cool If You Did," but in real life, he only has eyes for his wife, Miranda Lambert. In fact, the Oklahoma native is so devoted to his bride of almost two years, that he refuses to even play a love interest in any of his videos.

"Since I've been married, I won't go there in a video," he explains to People magazine. "If I was to go there, it would be Miranda in a video. I'm not an actor and don't pretend to be. Everybody knows I'm married to Miranda Lambert, and they don't want to see me leaving a bar with a girl. Why would I take this ring off for a video? I'd be insulted by that if I was Miranda, and I don't want to do anything to insult her or hurt her feelings."

The superstar couple have weathered their share of personal storms in the last few years, including the death of both Blake's father and a childhood friend of Miranda's. Add to that their sometimes lengthy separations, between their music careers and Blake's role as a coach on the TV show, "The Voice," and the twosome admit they have to work extra hard to make their marriage succeed, but the result is more than worth it in the end.

"When you get to celebrate moments like this together and when you go through the hard stuff together, those are the moments that actually count. All the rest is fluff," Miranda shared after the pair's recent ACM award wins (quote via Country Weekly). "Like I always say, my mom said to my dad, 'Divorce is not an option.' So, we really love each other and have a real marriage outside of all of this."

"The Voice" airs Monday and Tuesday nights on NBC at 8:00 PM ET. Blake's latest album, Based On a True Story ..., recently debuted at the top of the charts and Miranda's trio, Pistol Annies, will have their new album, Annie Up, in stores on May 7.
