why is jessica called the "ice princess"

because....one day,snsd went for a tv show tht i forgot wat its name is...when the mc was interviewing other members,she was just sitting leaning her back to the walls without saying anything or make any expression just like an ice..thts why ppl called her ice princess!

I think ppl call Sica ice princess becoz she posseses a cold attraction,and a thin solf voice.She has a unique female style like a princess.But with me i like a nick name "icescoop princess" that i heard on a tv show,icescoop means an icescream scoop princess,Sica is so sweet and silly at times,when other members r answering interview,Sica is out of space,her spirit hangs on ceiling.But sometimes she is dorky n becomes a poor victim of members prank.Yes,this is my icescoop princess Jessica Jung

Because she has a cold look
