Whether you love it or hate it, you can thank Ella Langley for Riley Green's mustache.

Ella was explaining backstage at the ACM Awards that she's the reason he's sporting that look. She was co-directing the video for "You Look Like You Love Me" and she wanted it to have that "old Western" look. "I told Riley that he could not shave his mustache off, at least for the music video," she says. "So here we are still, a year later, and I don't think he can get rid of the 'stache. We're stuck this way." Riley has even named it "The Conquistador."
