f(x)'s Krystal revealed that she has a humble opinion of her own physical appearance.

On the July 2nd broadcast of Mnet's 'Beatles Code 2', MC Tak Jae Hoon compared Krystal and�her older sister Jessica of Girls' Generation asking, "Who do you think is prettier?"

Krystal responded without hesitation: "Unni," referring to Jessica. Tak Jae Hoon then jokingly remarked, "We think she's prettier too," only to�later add, "I personally think Krystal's more pretty."

The f(x) member wasn't falling for it as she pointed out, "You just said that Jessica unni's prettier," and�the MC explained,�"That's just the popular opinion, I think you're prettier."

Krystal then surprised the MC panel revealing, "I won't acknowledge that. To be honest, I have a very common face. People have said, 'Krystal has the kind of face that you can see at any random middle school or high school'."

Sohee of the Wonder Girls, who also featured as a guest on the episode, commented, "I don't have a common face, but I think I have an ordinary face." However, she also mentioned that she feels she's the best looking out of her group, saying, "I love and am very dear to myself."
