Smith plays "Roulette" with Whitters

Co-written by Smith with Jessi Alexander, Chase McGill and Mark Trussell, the tune features Dobro as the pair sings of a gamble they know could end in devastation, but is still worth the risk. Directed by his brother and creative director Cooper Smith, the official music video for "Roulette On The Heart" was released two months ago.

"From the moment I wrote 'Roulette On The Heart,' it felt like finding a new level as a songwriter, and having Hailey Whitters believe in this song alongside me only took it to another level," said Smith. "This song feels like it could live for a long time."

Whitters said, "I first heard 'Roulette On The Heart' while playing radio shows with Conner Smith and was so honored when he asked me to sing on the song. I love how realistically the song captures the intoxicating and sometimes toxic feelings of being in a complicated relationship."

"Roulette On The Heart" is Smith's latest offering from his his debut CD, "Smoky Mountains" released earlier this year. The disc contains the GOLD-certified hit "Take It Slow" and two-week chart-topper "Creek Will Rise."

Smith just received his first ACM Awards nomination for New Male Artist of the Year on Tuesday, just days before he weds his fiancé, Leah Thompson.
