Girls' Generation member Tiffany's nickname was revealed to be 'Pink Pig'.

On the episode of MBC "Radio Star" aired yesterday, Girls' Generation members Tiffany, Jessica, Yuri, Sunny, and Taeyeon starred as guests on the show.

Host Kim Gura asked members: "I heard you guys call Tiffany 'Pink Pig'. Why is that?"

Tiffany responded that she was infatuated with the color pink. The other members testified to this, saying, "When we receive any gifts that are pink, Tiffany thinks they're hers".

Tiffany's roommate Sunny continued: "Tiffany eats a lot these days, so we always tease her by calling her 'pig'. Isn't the word funny?"

Tiffany grumbled at Sunny's comment, but confessed that she was the heaviest out of the Girls' Generation members, weighing 106 lbs.
