Liam Payne!

This photo of the singer wearing a black tee and a backwards hat looks just like something Justin would wear!

Liam was dressed like this to promote the bracelets that he's wearing. Check out all his tattoos – he has so many now.

We wouldn't be surprised if this were a joke between the guys, who are known to get along really well with Justin.
