Firstly, how is she only 21?

In case you don't have a phone, access to the internet or the use of any of your senses, Kylie Jenner celebrated her 21st birthday over the weekend. Yep, she's just 21 years old and she made sure we all knew about it this weekend when posting pictures from her glamorous party which included its own ball pit and personalised Barbies. However, that wasn't the only bash Kylie was the guest of honour at. The 21-year-old (we cannot get over it) also went to Las Vegas last night to celebrate round two and it looked just as lavish. Those lucky enough to receive the invite were BFF Jordyn Woods, Tiffany Sorya, Stassi Karanikolaou, Yris Palmer and her assistant Victoria Villarroel. The group went for a friends-only dinner in a local restaurant, where they did the ceremonial embarrassing of Kylie by singing her Happy Birthday, although she looks to be loving it. Boyfriend Travis Scott was performing in Sin City also, with Kylie and friends taking their place in the VIP booth to enjoy the performance. And what's a celebrity bash without a mid-night change of outfit? Yep, not only did Kylie have two birthdays but she also had two outfits for last night's celebration alone. Sharing a picture of her similar-yet-different outfit to the one she wore at her party in LA, Kylie revealed she chose to wear vintage Gucci for the second night of celebrations - as you do.
