Kaia Gerber Debuted a Broken Arm in a Bikini Selfie

On Saturday, Gerber shared a selfie of herself wearing an olive green bikini and a brand-new accessory: a giant blue arm cast that extended past her elbow. "Had a little accident but I'm okay!" she captioned the snap, which was followed by a copy of an x-ray illustrating the broken bone in her right arm.

It's unclear how Kaia broke her arm, but fellow model and friend Delilah Belle Hamlin has a theory. "Did you fall down those stairs?" she asked in the comments section of the post, referencing the flight of steps in the background of the photo. "Those stairs are certainly daunting," she added.

Meanwhile, another fan wondered if it was the result of her daily workouts with Dogpound trainer Kirk Myers. Earlier this week, Kaia and her famous parents, Cindy Crawford and Rande Gerber, FaceTimed with Myers for a high-intensity sweat session, and, by the looks of the cardio drills, it certainly seems like a possibility.
