This is one moment Kylie Jenner will never forget.
Kim Kardashian and Kanye West weren't able to attend the E! star's blowout 16th birthday bash on at the AT&T Center in downtown Los Angeles Saturday night, but something tells us Kylie was OK with their absence after receiving their gift—a surprise appearance by Drake!
"Kim and Kanye arranged for Drake to perform. It was a total surprise. Kylie had no idea. Drake was the big surprise," a source tells E! News.
Big Sean took the stage to perform at Kylie's party, when he was joined by the OVOXO rapper, completely catching Jenner off-guard.
Kris Jenner's assistant, Jen Stith, captured part of Drizzy's performance of "Versace" on video, which she posted on Instagram. Behind the rapper, Kylie, Kendall Jenner, Jaden Smith and a few more of her besties were dancing and rapping along to the hit.
"My night >> @champagnepapi," Kylie wrote, with a photo of Drake giving her a smooch on the cheek.
Kylie spent her special night with 200 family members and friends, including Hailee Steinfeld, Tyga and Willow Smith.
In lieu of gifts, guests were asked to bring an unwrapped toy for Children's Hospital Los Angeles, and 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, "had the time of her life," a partygoer told E! News. "It was everything she hoped it would be."
