Why so serious, Kim Kardashian?

Kim made the revelation in a tweet Monday along with a candid black-and-white photo from her family’s Christmas party of her and friend Shamari Maurice laughing it up and enjoying each other’s company.

While Kim -- ET's No. 1 headline-making celebrity of the year -- was all smiles for the holidays, the same can’t be said for her adorable 1-year-old daughter North West when she met Santa for the first time.
