Chris Brown and Justin Bieber have joined in the internet's strangest craze -- both stars have started planking.
Chris posted a photo of himself planking on a round shelving unit, with the caption "Plank!!!".
And Justin posted a photo of himself planking on a yacht, with the caption "Me and @Diggy_Simmons #plankin #schwag"
Planking has taken the internet by storm in recent months, and with participants taking photos of themselves lying like planks in unusual locations.
The trend hit headlines for all the wrong reasons in May when a 20-year-old man plunged to his death while planking on a balcony in Brisbane. Another young man was also arrested for allegedly balancing himself on a police car.
Do you think it's wrong that Justin and Chris are encouraging their fans to plank?
