She was just spotted in New York City clad in black with her signature locks, but it appears the proud mamma and newlywed has gone back to blonde! Kim just revealed on her Instagram that the blonde is back in a bigger and better way -- all over!

Kardashian took to Instagram and thanked hair colorist Serge Normant for her new blonde locks -- which look fab saying, "It's baaaaack!!!! #BlondeHairDontCare thanks to@SergeNormant.

However, it looks like we all may have been punk'd by Kim herself. Later in the evening, Kim revealed her new 'blonde' locks were actually a very good wig! Saying "It's just a wig! Looks so real though right?" Nice job Kim, you got us!!

We first saw Kim with blonde hair during her pregnancy with North, however, she quickly went back to her natural look after giving birth. Kim's hair color is constantly changing, but we're happy to see she's having a little fun with it. Regardless of whether or not Kim's hair is real or fake, what do you think of Kim as a blonde?
