Justin Bieber has been getting his celeb friends to promote his new single for him by posting pictures of them with a sign counting down until "What Do You Mean" is released.
Kylie Jenner did it.
Ariana Grande did it.
Ed Sheeran even made a song for it.
After seeing those pics, I bet you were wondering, how does this happen? How are the photos taken? How does it all work? Now we know exactly how to pose for those pictures, because Little Mix got caught by photographers in the midst of it all.
