In the video shared on both stars’ social media, Derulo and Smith are practicing golf, with Smith showing Derulo how to perfect his swing.
As Smith helps Derulo set it up, the pop star swings, and whacks his golf club straight into Smith’s face.
What appears to be a tooth flies onto the floor, and Smith crawls towards the camera to inspect his front teeth, which are somehow now chipped cleanly in half.
"Put some ice on that," Derulo suggests, to which Smith says, "It's my turn. It's my turn. I only need one swing."
The video finishes with a freeze frame of Smith hitting Derulo with his golf club.
As the corn was spinning on a power drill (do not attempt at home), Derulo let out a yell and revealed his front teeth were missing - in a suspiciously similar shape to Smith’s missing teeth.
Derulo was then spotted in Los Angeles afterwards sporting a row of completely intact pearly whites.
