Bella Hadid's Birthday: Chocolate-Brown Mermaid Waves

Friday, October 9, marked Bella Hadid's 24th birthday, and the supermodel went all out with a new hair look, because well, why not? Color-wise, the star opted for a medium chocolate-brown shade that's decidedly lighter than the ultra-dark, almost-black hue she had before her birthday. The model and new aunt shared several snapshots from her birthday festivities — including a hilarious video clip of her doing an impression of Kylie Jenner from this past week's episode of Keeping Up With the Kardashians. In the video, you can see that Hadid's hair is especially wavy and has an undeniably mermaid-like feel to it.
