Ariane Grande has joined the growing list of celebrities going platinum blonde. The "Side to Side" singer first posted a picture of her new hair color on her Instagram feed on Halloween. On Monday, the singer followed up with two new posts, proving that the hairdo wasn't just a Halloween costume. While it may seem like a coincidence that so many celebs are opting for the icy look, celebrity stylist Chris Appleton is the man responsible for both Kim Kardashian West and Ariana's platinum locks.
