Hey guys well no one has answered the second Christmas question that I asked. So I will ask it again and remember that the winner will win either their choice of 15sd in gifts from the suite or a hot buys item. Ok so here is the question once again and remember to post the answer in the comments section of this post. What is the most heard Christmas Carol during Christmas? Ok so have fun answering it and the FIRST correct answer will win their choice of prize. Happy Holidays from The Stardoll Prizes Judges!
