[Picture] Dong Hae and Amber snapped a playful selca!

There are fans who told me that Super Junior's Dong Hae and f(x)'s Amber resemble each other so much and i doubted that at first.

However,after seeing this photo,i am doubtful whether they are real siblings or not,OMG,they look like each other so much.

What do you think?? Sharing is sexy
