The Real Housewives of Orange County stars Vicki Gunvalson and Tamra Judge were hospitalized as a result from an off-roading mishap in the California desert on Saturday.

The two reality stars were joyriding on all-terrain vehicles in Glamis, California, when one of the vehicles rolled over multiple times, reportedly while cameras for the Bravo reality series were filming, according to TMZ.

A source close to Gunvalson tells ET, "They're OK. Both sore but thankfully, they're both fine."

The Imperial County Sheriff's office confirmed to ET that two ambulances and an emergency airlift helicopter were put on standby for two injured riders, and a sheriff's deputy was also dispatched to the scene.

While the sheriff's office did not confirm the identities of the injured riders, they did confirm that both parties were transferred to the hospital -- one was taken by ambulance while the other was airlifted. Gunvalson, 54, was reportedly transported by airship, and neither party is believed to be seriously injured.

On Sunday, Judge, 48, reached out to her fans about the frightening incident with a post on Instagram, writing, "Thank you for your prayers and concerns. We are both beat up but very lucky to be alive. I've never been so scared in my life. As the driver I have an overwhelming amount of guilt and just happy that the 4 of us are alive."

Earlier in the day, Judge also shared a sweet snapshot of her son, Ryan, and her granddaughter, Ava, out in the desert, which she captioned, "Glamis baby."

It's possible the vehicles in the background were the ones they were riding when the accident occurred.

ET has reached out to reps for Gunvalson and Barney for comment.
