Kylie Jenner turned 17 on Sunday, Aug. 10, and the youngest member of the Kardashian clan had a weekend-long celebration including custom cakes, VIP serenades and a family dinner!

Kylie's celebrations began on Saturday, Aug. 9, with a pre-birthday party thrown for the stunning reality TV star by rapper Tyga. Guests included Justin Bieber, Chris Brown, The Game and, of course, sister Kendall Jenner.

"It was extravagant!" a source told Us Weekly. "Tyga had two custom cakes made for her and he asked Justin Bieber to sing her 'Happy Birthday.' And he had hats made with her photo on them."

Giving thanks to her pals for the birthday love, Kylie shared a snap of her wearing one of the personalized hats via Instagram the next day.

"Thank u everyone & T for the cake & JB for singing happy bday to me," the birthday-girl wrote. "I love u guys."

Kylie wasn't the only one who took to Instagram to celebrate her actual birthday. Mom Kris Jenner and sisters Kendall and Kim Kardashian shared a host of super-cute throwback pictures of Kylie through the years as they wished their famous family member a happy 17th.

And, of course, one birthday bash wasn't enough for this famous teen. Despite the Teen Choice Awards falling on her actual birthday this year, Kylie's relatives managed to make time for a second birthday party on Sunday evening, this time at celeb-favorite eatery, Nobu Malibu.

After walking the red carpet and appearing on stage at the high profile event, Kylie jumped in a car with sister Kim and dashed to her second birthday party. Enjoying the scenery, North West's mom posted a photo of the sun setting over the ocean later that evening, with a caption, "Nobu Malibu bday dinner for Ky."
