Blake Shelton earned a No. 1 hit with "My Eyes," the fifth single from his 2013 album Based on a True Story .... The song, which Shelton sings as a collaboration with friend and former The Voice Team Blake contestant Gwen Sebastian, begins with the lines "Those high heels with that sundress / Turquoise heart hanging 'round your neck / Red lips like wine, wanna drink 'em up / And keep on drinkin' 'til you make me drunk," setting the tone for one of the sexiest songs Shelton had released so far in his career.

"My Eyes" stayed at the top of the charts for three weeks and helped Based on a True Story ... win Album of the Year at the CMA Awards. Below, Tommy Lee James, who co-wrote "My Eyes," shares the story behind the song with The Boot.

I was glad I showed up that day.

I wrote that with Josh Osborne and Andrew Dorff. We got together, we sat down, and we chatted for a while. Josh goes, “I have this idea. I don’t know if it’s any good or not. But the hook is 'My eyes are the only thing I don’t want to take off of you.'"

We were like, “Oh my God, we have to write that.”

It really happened pretty fast, but it’s always a fun write. Some of those lines in there remind me of Andrew and the quirky ways he would come up with stuff nobody else would come up with. It’s actually a really, really, deceptively hard song to sing, and Blake’s version is really great. Blake’s such a good singer.
