Kylie Jenner Shaves Her Head, Gets Birthday Wish From Justin Bieber

Kylie also gets plenty of b-day love from her Kardashian sisters.

Kylie Jenner certainly made it a 17th birthday celebration to remember.

The reality TV star celebrated her birthday on Sunday at the Teen Choice Awards, where she not only won an award, but proudly showed off the gift that she gave herself: a shaved head.

"I shaved the back of my head for my birthday," she told E! News on the red carpet. "I was just doing my hair and I was like: ‘Why not shave the back of my head?"

But, shaving her head wasn't the only way she celebrated. According to US Weekly, Tyga threw Kylie a b-day bash, with guests including Chris Brown, The Game and Justin Bieber, who reportedly sang her Happy Birthday.

Justin took to Instagram to publicly wish Kylie a happy birthday, posting a photo of her with the caption, "Happy birthday @kyliejenner ;) glad I got to spend it with u. So dope watching u grow up."

Kylie then posted her own photo from her party, showing off her cake and thanked "JB for singing happy bday to me."

Kylie's famous Kardashian sisters also got in on the b-day action. Kourtney and Khloe, who were both "so sad" to miss out on the festivities, posted adorable collages of pictures of themselves with Kylie.

But Kim decided to embarrass her little sister just a little bit, posting 6 selfies that Kylie took on her camera when she was 9 years old. Wonder if they will make Kims upcoming selfie book?
