Miranda Lambert says she knew that Blake Shelton was “off limits” when she first met him. In an interview with Dateline’s Hoda Kotb, Miranda says she immediately felt a connection with the "Honey Bee" singer, but there was one tiny problem.

“I knew he was married,” says Miranda. “I had seen their wedding picture in Country Weekly. I knew better,” she continued, “like, this is off limits. My parents are private investigators for God’s sake. I’ve seen this my whole life—affairs. Of all people to know better, I know better than this.”

Blake married his first wife, Kaynette Williams, in 2003; the pair divorced in 2006. Miranda first met Blake when the two were paired for a duet of “You’re The Reason God Made Oklahoma” during CMT’s 100 Greatest Duets special in 2005.

“I didn’t know what to do with it,” she says. “It was, like, my first duet with some other country star, and I didn’t know if it was just initial butterflies because of that. I don’t know what it was. It was just this draw to each other.”

Blake and Miranda wed in May of this year in Texas.
