I wonder if Kim Yu-Na has done any plastic surgery. South Korea is the king of plastic surgery. She looks all natural to me though. Asian plastic surgery probably not needed.
Here is Yuna Kim skating to James Bond in the Skate America 2009. For the 007 skate by Kim Yu-Na Bond in the Olympics, go to here. NBC won't let you embed 2010 Vancouver Olympics video of the Kim Yuna James Bond dance.
However you spell Kim Yu-Na boobs or Yuna Kim boobs or Kim Yu-Na boobs, they are a sight to be seen.
As some would say - Kim Yu-Na is hotter than the Esurance Car Insurance or Progressive Auto Insurance girl. People would buy any sort of insurance from her. With all the gold she will, Yuna Kim boobs might have a lot of cash for gold to sell.
