Kaia Gerber just unveiled a sleek new short haircut for summer 2019, and we couldn't be more obsessed. The 17-year-old supermodel took to Instagram for her big reveal, captioning the post, "the drama cut by @guidopalau @sandyhullett." Previously, her dark strands had been down to her shoulders in a no-frills style, but now she's sporting a full-blown bob and it's a refreshing departure from her signature look. Will Gerber keep her short hair around for the whole summer? We'll just have to wait and see.
