Sam Smith Radio

Sam Smith flawlessly sang Beyonce's "Flawless" and Destiny's Child's "Say My Name" ... but not at his show - at KARAOKE! And it was amazing!

The singer hit up a karaoke bar in Nashville this week after his concert. He shared on Instagram that he had the "best night EVER" ... and why wouldn't he after singing Queen Bey?!
