IU revealed her jealousy toward her older sister.

In KBS 2TV "Hello" aired yesterday, a girl came out and shared her stress of her older sister yelling at her for gaining weight. After listening to her story, IU said, "Sisters have something like that."

She continued, "I have a smaller figure but my sister tells me I'm too flat." The MCs then asked, "Then does your sister 'have more'?" and IU said, "My sister has a glamorous body."

The MCs once again asked, "Are you jealous?" and IU replied, "Yes," arousing laughter.
