Jessica poses with her "little brother"

Everyone knows that Jessica has a beautiful younger sister in Krystal, but did you know she also has a handsome 'younger brother'?

On her new Weibo account, Jessica wrote, "With my little brother hahaha ". Her 'little brother' was really good looking indeed, with short black hair topped by a beanie.

Of course, the 'little brother' she's referring to is actually Krystal with short hair. With the short hair and boxy shirt, Krystal looks like she can pull off a cross-dressing look perfectly. Her beanie may suggest that she may be wearing a wig, but do you think this new hairdo might mean f(x)'s comeback is very near?
