Kaia Gerber is healing up.

On Saturday, the 18-year-old model shared a picture to Instagram, revealing a blue cast that stretched from her upper left arm to her palm.

Gerber also dropped jaws by donning a dark green bikini in the photo, revealing her slim figure.

The post contained a second photo as well – an image of an X-ray displaying a broken wrist.

"Had a little accident but i’m okay!" wrote Gerber in the caption.

In a video shared on YouTube on Friday, Gerber addressed the cast, which she called her "uninvited guest."

"I actually broke my wrist yesterday, she explained. "I was in a little bit of an accident. Thankfully, I am OK, everyone is OK and this is the worst of the injuries so I feel very grateful."

Gerber, who is the daughter of supermodel Cindy Crawford, offered no additional details on the break.
