Kendall Jenner Had Her BIRTHDAY PARTY In Los Angeles . . . And All The KARDASHIANS And Their MEN . . . Were There!! (Last Night Kendall FINALLY Looked Better Than KYLIE)

The entire Kardashian Klan and their celebrity guests went to Kendall's birthday celebration at Nice Guy in West Hollywood. Kendall had some of her exes at the party, including Jaden Smith and Justin Bieber.

Only sister Kylie bucked the family memo and wore a bright orange jumpsuit – though her boo Tyga, who was also at the party, didn't seem to mind..see more photos
