Kelly Osbourne suffered a seizure today while on the set of her E! series Fashion Police.

A spokeswoman for Osbourne said that the 28-year-old TV personality is awake, alert and in stable condition.

Osbourne reportedly told guest host Melissa Rivers, who was filling in for Giuliana Rancic, “I don’t feel good” before falling out of her chair. She then began shaking and an ambulance was called to the scene.

Kelly will be staying at the hospital overnight for observation as a precautionary measure.

“She’s fine,” Rivers said in a video posted Thursday afternoon on TMZ. “We just saw her.”

No additional details were provided.

Osbourne shared a photo of her IV insertion wound saying, “Thank U all 4 UR beautiful well wishes yes I did have a seizure they are just trying to figure out why?”
