Kelly Osbourne Hospitalized After Seizure

'Fashion Police' co-host falls to the floor during Thursday's taping.

Kelly Osbourne has been taken to a Los Angeles-area hospital after having a seizure on the set of her E! show "Fashion Police."

"Entertainment Tonight" reports that Kelly had just finished a one-hour taping, shortly before noon Thursday (March 7), when she suddenly fell to floor.

"Fashion Police" executive producer Melissa Rivers, who was filling in for Giuliana Rancic on the show's panel, and several crew members came to Kelly's aid. An EMT happened to be in the audience and was able to provide some assistance during the short episode, which lasted about 30 seconds. Kelly came around on her own, but was still taken to the hospital for further evaluation.

When reached by TMZ, "Fashion Police" host Joan Rivers said the former "Osbournes" star is doing "fine" after the incident.

Kelly isn't the only Osbourne facing health issues: Her brother, Jack, was diagnosed with multiple sclerosis last year, and mom Sharon is a colon cancer survivor.

Kelly has taken some heat over the negative nature of "Fashion Police," most recently from pop superstar Lady Gaga. Late last year Kelly told the U.K.'s Fabulous magazine that Gaga's fans "are the worst" because of their criticism of her weight and said Gaga should try to stop them. Gaga responded with an open letter , in which she let Kelly know she didn't appreciate being taken to task.

In fact, Gaga claimed Kelly's entire E! show was built upon bullying. " 'Appearance' is the most used reason for bullying in the world. Your show breeds negativity, and over the years has even become comedic in nature," Gaga wrote. "It glorifies you and Joan Rivers pointing in the camera, laughing, and making jokes about artists and celebrities as if we are zoo animals. What about your body revolution? It used to make me truly sad when I would hear people talk about your weight when you were younger, as I was bullied too. To see you blossoming into a beautiful slender woman who makes fun of others for a living is astounding. Why not help others? Why not defend others who are bullied for their image and share your story?"
