Emily Ratajkowski steamed up the Golden Globes red carpet with dramatic slit

New hair, new her.

Emily Ratajkowski's long bob made its red carpet debut at the Golden Globes Sunday, a sophisticated departure from her default beachy waves.

She paired her new look with a plunging Lemonade-yellow gown by Reem Acra, with a sparkling necklace/tie neckline and a dramatic slit.

But did Emily actually cut her hair, or is she just hiding her longer tresses? Some Twitter users supposed that her "haircut" is actually just a sneaky styling move.
