Aside from the exaggerated decorations and the more exaggerated costumes, there was one surprise that managed to keep everyone wide open - a performance by singer Sia who appeared in a holiday gift box and sang her lavish repertoire with the freshmen sisters raising Stories as the last fans and singing along with her.

If that's not enough, one of the most prominent gifts under the Christmas tree was that of Kenya and Kim to their daughter North - the original jacket Michael Jackson wore while spending time with Elizabeth Taylor. This is a velvet jacket with side chains.
