Everyone sings in the shower now and again, but it probably doesn't sound quite like this.

Grammy-nominated crooner Sam Smith proved he's just like the rest of us, singing a bit of Beyonce's "Drunk in Love" while he was scrubbing up recently.

The 22-year-old Brit's boyfriend, Jonathan Zeizel, captured the serenade on video from the other side of the bathroom door, and posted it on Instagram, writing, "Sam or Bey?"

No word on if Beyonce's seen the video yet, but chances are she'd think it's ***flawless.
