The 25-year-old rapper splashed out on a white Ferrari 482 Italia for the birthday girl and presented the $320,000 vehicle to her outside Bootsy Bellows, the Hollywood hotspot where Kylie held her party on Sunday (09.08.15).
Kylie, who wore a platinum blonde wig for her birthday, was visibly shocked by the extravagant purchase.
The reality TV star made her birthday a family occasion and was joined at the club by her sister Kendall Jenner, half-sisters Kim, Khloe and Kourtney Kardashian, parents Kris and Caitlyn Jenner and brother-in-law Kanye West.
Famous friends who showed up to celebrate with the birthday girl included Zayn Malik, Gigi Hadid, Joe Jonas, Hailey Baldwin and Pia Mia.
Kylie started the night with a meal at The Nice Guy in LA, owned by the h.wood group, which also runs Bootsy Bellows.
Sunday was the second celebration so far for Kylie, who joined her family for a fancy dinner at Nobu in Malibu on Friday night (07.08.15).
And she also took time out from celebrating to visit the LA Children's Hospital, where she gave out gift bags to young patients.
