Kendall Jenner turned 21 and had a big party to celebrate. When her biological father, Caitlyn Jenner showed up things got super awkward according to reports.
All her sisters and her mother Kris Jenner were there, and they seemed to shun Caitlyn and not talk to her much. This may be because Caitlyn was dressed quite casual while the rest of the party was dressed up for the occasion. Or it could be because Kris Jenner did not want Caitlyn to be there at all in the first place. Whatever the case, Caitlyn was invited so it seems awkward that they would treat her that way.
