The actor Joo Sang Wook was forced to reveal his ideal type by none other than his own mother.

On the latest episode of his variety program, 'Qualifications of Men', the actor embarked on a vacation with his mother. At a brief rest stop, she expounded on his ideal woman.

"My son likes women who are at least ten years younger than he is," she claimed, to his great embarrassment. "She should be slender and have long hair."

She also let the viewers in on his current dating status. "I'm positive he doesn't have a girlfriend right now," she said. "When he does, he always goes into his room and whispers into the phone, but he doesn't do that nowadays."
