Kim Kardashian and Justin Bieber reunited last night at the Z100 Jingle Ball held at Madison Square Gardens in New York. But fear not little Bieberettes, his real life girlfriend Selena Gomez also attended the event.  Earlier in the week Justin and Selena were seen on a pancake date leaving iHop and if there are pancakes involved you know it’s for realz.

Katy Perry attended dressed oddly in that unflattering bathing suit style I am learning to detest. I like her when she dresses classic and elegant.

Also Jingling his balls at the event was her ex Travis McCoy. I wonder if this is the first time they have seen one another since they last split up? Like she cares? She’s got Russell Brand.  Bitch.

Lots of others attended and can be seen in the pics below.
