Jessica and Krystal revealed how they felt growing up as sisters. The two famous celebrity siblings made the cover of 'Cosmopolitan' magazine's November issue.

Jessica showed love for her little sister, saying, "Krystal always had a more kind image. At 3 years old, she had round eyes and pale skin, and even the young me thought she was pretty." Krystal also said, "Unni was pretty when she was younger, but I think she shines most right now. I think she's finding what's most like herself."

How sweet! The two sisters also look chic, feminine, and amazing on the cover. Don't you think?
