Jason Derulo and Will Smith have gone viral online after Derulo appeared to knock out Smith’s front teeth with a golf club.

Singer/songwriter Derulo, 30, was learning how to play golf on a virtual course as actor Smith, 51, helped with his swing in a new TikTok video.

Before Derulo took his first shot, Smith says: “Wait, hold it. Don't swing yet.”

But as Smith prepared to step back, Derulo swung the golf club and knocked out Smith’s two front teeth.

Derulo told him to ‘put some ice on that’ as Smith fell to the ground.

Afterwards Smith showed off his new smile to his 47.8 million Instagram followers with a selfie of the pair, writing: “I gotta stop inviting @jasonderulo over (see my last post)."

Durelo added: “He’s finally embracing his new smile. @willsmith See my last post.”

Fans were quick to comment on the video which has been viewed over one million times, as one wrote: “Good photoshop."

Another said: “Nah this can’t be real lol. Those Hollywood special effects.”

One user added: “You play too much" as one user said: “That Will Smith and Jason Derulo video has me in tears.”
