Talk about a sweet 16.
Kylie Jenner rang in her big 1-6 with a huge birthday bash at the AT&T Center in downtown Los Angeles Saturday night, with the Keeping Up With the Kardashians star partying the night away with 200 family members and friends, including the likes of Hailee Steinfeld, Tyga, Willow Smith and Jaden Smith.
The birthday bash, organized by celeb event planner and Kardashian family friend, Sharon Sacks, had an Alice in Wonderland theme, complete with a Dylan's Candy bar and giant mushrooms, as well as a custom cake whipped up by Hansen's Cakes.
Kim Kardashian didn't attend the fête, as she stayed home to take care of daughter, North, an in-the-know partygoer told E! News. But Kim did make an appearance via a "Happy Birthday" video message.
And Kendall also had a special video for her sister, which included vintage pictures and videos of the two of them together.
In lieu of gifts, guests were asked to bring an unwrapped toy for Children's Hospital Los Angeles, and on their way out of the affair, they received gift bags that included headphones, IPod speakers, Kardashian Beauty makeup and jewelry from Kylie and Kendall's PacSun and Metal Haven jewelry line.
The birthday girl, who wore a black leather Thierry Mugler skirt and black Nicholas tank top for the occasion, "had the time of her life," a partygoer told E! News. "It was everything she hoped it would be."
There was also a huge surprise musical guest.
Drake hit the stage with Big Sean and surprised Kylie with a rock star performance!
Tune in to E! News at 7 p.m. and 11:30 p.m. Monday for all the details of the big bash.
Happy Birthday, Kylie!
