LOS ANGELES (AP) — Yes, that really was a wigged Kristen Wiig dancing during Sia's performance of "Chandelier."
The former "Saturday Night Live" star pulled off possibly the best kept secret of the 2015 Grammys with her cameo alongside teen dancer Maddie Ziegler as Sia sang obscured in the background.
The "Bridesmaids" star wasn't among the announced celebrities attending the ceremony, nor was she even rumored to be appearing in Sia's kinetic performance, which was introduced by Shia LaBeouf. Wiig didn't walk the red carpet ahead of the show either.
