I went to Kim Kardashian's book signing event, and it was complete chaos

A book signing for Kim Kardashian West's "Selfish" at a midtown Manhattan Barnes & Noble Tuesday started out as a peaceful gathering of fans, but soon turned tense as animal rights activists transformed the gathering into a protest and a few fan altercations took place.

The book, which debuted this week, is full of selfies - some never before seen by the public - of Kardashian and her friends and family.

The star was at the store to meet and greet fans, and we went to check out the scene.
