T-ara’s Hyomin, Rainbow’s WooRi Separated at Birth?

On January 11, fans posted a photo compilation of T-ara’s Hyomin and Rainbow’s WooRi looking like twins.
In the first picture, WooRi is seated in the airport waiting for her flight to Japan for the “Golden Disk Awards in Osaka“. The second picture show’s Hyomin wearing sunglasses similar to Hyomin’s.  
 Hmm…maybe it’s me, but, the only thing that looks similar in these pictures are their sunglasses…
The second set of pictures seem to be made up of pictures taken on their cell phones. WooRi is on the left with a rose tucked behind her ear, and Hyomin is on the right flashing the camera a peace sign. They look more like twins in these pictures! 
 What’s the verdict? Separated at birth, or just a slight similarity?
