The cast members of 'Book of the House of Gu' brought laughter on set recently when they dressed up in female hanbok, traditional Korean garb.

Standing between the two feminine actors, miss A's Suzy is looking up at her two co-stars, Lee Seung Gi and Sung Joon, with an air of amusement and a little bit of not-unfounded apprehension.

Lee Seung Gi, in particular, looks like he would be good at playing female roles in the future! Maybe we'll be seeing him in an alternate-universe version of 'You're Beautiful' soon?
