Chris Young and Cassadee Pope performed the lovesick duet "Think of You" at Sunday night's (April 3) 2016 ACM Awards.

Young and Pope were a visual contrast, with him dressed in all black and her shining in a glittery gold jumpsuit. The real focal point, though, was the duo's vocal chemistry as they belted out lines like, "It's like there's always an empty space / Those memories that nobody can erase / Of how bright we burned / Well now it hurts, but it's true / When they think of me, they think of you."

"Think of You" is the second single off of Young's album I'm Comin' Over. It follows his No. 1-reaching first single, also titled "I'm Comin' Over."

When it came to choosing a duet partner, Young says that after seeing Pope perform at an acoustic radio station event, he knew he wanted her on the song.

"She's definitely somebody that can sing her butt off," Young tells The Boot. "And that was really the defining thing in me wanting to ask her to do a duet: she has an amazing voice. She's an amazing artist."

Along with his performance with Pope, Young is nominated for Album of the Year (for I'm Comin' Over) and Single Record of the Year (for the single "I'm Comin' Over").

Young is currently on tour with Pope as a special guest. For more information and tour dates, visit ChrisYoungCountry.com.
