It's well-known that the resident sibling duo of K-Pop, 2NE1's Dara and MBLAQ's Thunder, share a very close relationship. Dara confirmed it even further earlier today with a cute couple-like photo!

"Even today, we're close siblings!!! Dara and Thunder ^.^" she posted to her Twitter. With the younger brother displaying his shocking pink hair and the older sister shooting off a cute V-sign at the camera, the two siblings laid claim to one of the best-looking brother-sister couples in K-Pop!
