Sunny recently updated her Instagram with very cute pictures of herself and fellow Girls' Generation members Tiffany and Taeyeon all dressed up as Sesame Street characters for Christmas themed pictures!

She wrote, "An early merry, happy, sunny Christmas.  Elmo & Cookie Monster," and, "Merry! Happy! Sunny! Christmas."

In the pictures she posted, the three girls look adorable in Elmo and Cookie Monster hats as they stand in front of a brightly lit Christmas tree!
