Kendall Jenner is finally 21!
Although the model's birthday is today, Nov. 3, celebrations were in full swing last night during her party at West Hollywood hotspot Delilah's.
The brunette beauty had quite the guest list, with not only her famous family in attendance, but also artists such as Big Sean and Travis Scott. Kim Kardashian is rumored to have made an appearance, though there's no photographic proof she was there.
