Kylie Jenner turned 17 on Sunday, and she celebrated her big day–as well as the night before–with a group of fellow celebs including Justin Bieber, rapper Tyga, Chris Brown, The Game, and sister Kendall Jenner. Her party was replete with party hats featuring Kylie’s own face, as well as cupcakes, and some music courtesy of the Biebs.

Justin Bieber even lauded the birthday girl by posting her photo on his Instagram account.

“Happy birthday @kyliejenner ;),” he captioned the shot. “glad I got to spend it with u. So dope watching u grow up.”

This is kind of funny since it makes Justin Bieber sound like a much older man, when in fact he’s only about three years older than Kylie Jenner.

Tyga posted a photo of himself with Kylie Jenner to his Instagram account, captioning it simply, “bday girl.”

On Saturday evening, The Game shared a photo of some of the birthday party gang while outside dancing. His photo features Kylie’s big sister Kendall Jenner with Chris Brown. The Game captioned this shot, “#Backyard boogie.”

Might there have been more than just dancing going on?

TMZ reports that Tyga was about four years early when offering Kylie Jenner a shot at her pre-birthday festivities on Saturday night. They feature video footage on their site that leaves little doubt about this being the truth.

Members of Kylie Jenner’s family helped celebrate her birthday on Sunday, including Khloe Kardashian, who created a montage of all things Kylie for Instagram.

“Happy birthday to my sister, spirit animal, partner in crime and best friend! @kyliejenner you constantly amaze me with your wisdom, maturity, sensitive soul, confidence…. I could go on for hours and hours. You and all of my siblings have given me enough love to last me lifetime after lifetime. I wish you and incredible birthday and I’m so sad I’m not with you today. This only means we get to celebrate your birthday when I’m back,” Khloe wrote as the caption.

Big brother Brody Jenner even got in on the fun, sharing a shot of him with his baby sister. “Happy Birthday to my beautiful little sister @kyliejenner love you,” he added.

Mom Kris Jenner and sister Kendall Jenner shared photos of Kylie and Kendall together.

“Happy Birthday to my precious baby girl @kyliejenner !!! You are such a bright light in our family and always bring love, laughter, your amazing energy and your endless imagination to every day!! Your huge heart and delicious hugs make me even more proud of you. I love you so very much and thank God every day for blessing me with you! #cherish #youwillalwaysbemybaby,” the Keeping Up With the Kardashians momager wrote.

Kendall captioned her shared shot, “happy birthday to my teeny tiny baby sister @kyliejenner I love you!”

Kylie Jenner must certainly feel loved. From her gang of friends who danced and sang for her and her family who showered her with love and memories, it sounds like both Saturday night and Sunday were exciting days for Kylie.

Can you imagine how much more exciting her celebration will be next year when Kylie Jenner becomes a legal adult–and then three years after that when she can drink legally, too?

Of course her tender age likely didn’t prevent Kylie from taking that shot on Saturday night–do you suppose?
