f(x)'s Krystal and Amber opened up about their ideal types on the latest broadcast of 'Old School'.

Special DJ Super Junior's Kangin asked the two "4 Walls" singers who they'd like to work with and what kind of boyfriend they'd like to have. Amber answered, "Orlando Bloom. I like everything about him. I feel like the roles he takes on are innocent and quiet yet cool at the same time."

Krystal added, "One time, Amber said that a staff member with a good body was her ideal type. She said, 'That oppa is cool. He's my ideal type.'" She also mentioned who she herself would like to work with, "Johnny Depp. He's masculine. He plays characters who have their own personalities, and I think the aura he has is different."
