Athlete and 'Roommate' cast member Song Ga Yeon went through a shocking transformation on the latest episode!

Normally a very casual dresser, preferring sweatshirts and athletic clothes over anything else, roommate Lee So Ra made it her mission to transform her wardrobe into something better suited for her pretty face.

Everyone was shocked when she finally revealed the results of her work, with Song Ga Yeon rocking a one-piece strapless dress in jet black. "I saw her and she looked like Beyonce," Jo Se Ho commented.

Even After School's Nana, one of the prettiest idols in the business, was impressed. "I always thought of her as a little sister, but seeing her like this, she's a really sexy woman," she said.
