Sure, we all sing in the shower sometimes, but it doesn't sound anything like this. Sam Smith's boyfriend, Jonathan Zeizel, caught the singer belting out tunes while he was in the shower, and if you're wondering about his song of choice, it's none other than Beyoncé's "Drunk in Love." This isn't the first time we've heard him sing another artist's work. Sam has covered other popular songs before, including Tracy Chapman's "Fast Car," and several artists have covered Sam Smith too, including both Kelly Clarkson and Ed Sheeran. Listen to Sam sing Beyoncé's hit now, and then check out more must-see viral videos.
