2AM's Im Seulong recently uploaded a photo of himself posing with Brown Eyed Girls' Ga-In and 2PM's Taecyeon. Seulong tweeted, "At the University Music Festival with my loves kek, the ghost on the left is also my love keke, who do you think it is?" In the photo, you can see the two tall male idols towering over the tiny Ga-In, while another mysterious, blurred figure got snapped trying to join the picture. Who do you think the mysterious figure is? Source: Im Seulong's Twitter Tip: Brittany
