Luke Bryan has shared some marriage advice with his American Idol coworker Katy Perry, ahead of her marriage to Orlando Bloom. It’s not one you haven’t heard a million times, but it is solid advice. 

Luke wasn’t invited to Perry’s wedding but still offered his friend some advice before her big day:

“Marriage is a living, breathing thing… it might sound cliché… but just don’t go to bed mad at each other.” He added, in an interview with People Magazine, “Even if you do go to bed mad at each other, don’t let it snowball.”

“Me and Caroline get at each other as much as anybody, but we try not to let it drag out and or bury our problems”
