Smith made a decision to show his moves on top of the Chain Bridge in Budapest, Hungary.
The video shows Smith in Budapest, scaling a bridge, climbing on top of a building, and filming himself doing "the shiggy" to the Drake song with the help of a drone.
"Since then, celebrities including Ciara, Russell Wilson, Sterling K. Brown, Kevin Hart, James Harden, Odell Beckham Jr. and Lil Jon have all gotten in on the #DoTheShiggy dance, which has transformed into an Instagram-wide "#InMyFeelingsChallenge.
"I woke up this morning in my feelings and I was like, 'I got to let them out, '" the Suicide Squad star explained in an Instagram video on Thursday. "I'ma Keep It 100..." I was TERRIFIED up there. Smith, 49, did the routine on top of a bridge in Budapest - which is why he says his moves are "stiff".
The rapper-turned-actor's video quickly went viral, racking up a whopping 7.3 million views so far. The challenge even got a nod from Drake himself.
