Most 21-year-olds get one week of parties at most to celebrate the big milestone. Jordyn Woods, Kylie Jenner's best friend, got two weeks and 3+ parties now. Last weekend, it was a Thursday birthday dinner and a Friday lavish birthday luncheon and evening bowling party in Los Angeles to mark her birthday and the launch of her and Jenner's Kylie Cosmetics collection. (Woods turned 21 on that Sunday.) This weekend, it was another party on the other side of the country in Miami.
