Kendall Jenner & Famous Friends Pose in Birthday Photo Booth

Kendall Jenner works on her fitness with Hailey Baldwin and some other gal pals while hiking on Tuesday (November 3) in Los Angeles.

The 20-year-old model took a ride in her new classic car after grabbing breakfast at the Beverly Hills Hotel earlier that morning.

The night before, Kendall celebrated her birthday with a big party at the Nice Guy.

A bunch of her famous friends attended the bash and shared pics from the photo booth on Instagram, including her sisters Kylie, Kim Kardashian, and pal Justin Bieber.

“Happy Birthday to my little Kenny!!!! You’re not a teenager anymore! I love you so much and am so proud of everything you have accomplished and the person you have become!” Kim wrote.

Justin captioned a pic, “What a beautiful family inside and out happy birthday Ken.”
