Kendall Jenner looks full of cheer as she joins sister Kim Kardashian and mom Kris Jenner at star-studded party

Kendall Jenner stole the show at Shelli Azoff's Christmas bash at The Forum in Los Angeles on Wednesday.

The 21-year-old's smile lit up the room, even as she posed next to a fully-decorated, bright and shiny tree.

But the Keeping Up With The Kardashians star didn't come alone. She was accompanied by her famous sister, Kim Kardashian, who has been shying away from the public eye lately, and her mother, Kris Jenner.

Kendall's famous sister has been staying near her LA home since her Paris robbery in October and Kanye West's mental breakdown a month later that sent him to UCLA Medical Center for a 5150 hold.
