Girls' Generation's Jessica as well as Seohyun and Yuri were guests on the March 12th broadcast of 'Jo Jung Chi and Harim's 2 O'Clock' radio show.

 

The DJs brought up the girls' nicknames, saying, "Do you want to change your nicknames, 'Ice Princess' Jessica, 'Smooth Body' Yuri, 'Disciplined Life' Seohyun... Jessica, are you satisfied with your 'Ice Princess' nickname?" 

Jessica responded that it was all right, but the DJs mentioned that there was a new ice princess in town, Elsa from 'Frozen'. Yuri then told Jessica, "Aigo, you lost."

She also talked about her younger sister, f(x)'s Krystal, saying, "I was so happy to have promoted at the same time as Krystal. She's family, so I could talk about everything and tell her everything. I've told her a lot of my secrets."
