Julia Alexander King, who divorced the TV star in 1992, was driving home in New Jersey on 4 July when she collided with a car carrying a family of four, who were driving back from a nearby fireworks display.
One male passenger had to be cut out of the vehicle and he's currently in a wheelchair with unspecified injuries, reports TMZ.com.
A police spokesperson tells the website, ""All occupants of both vehicles sustained injuries.""
No arrests were made although an investigation is reportedly taking place into the incident. No details of King's injuries were available as WENN went to press.
