The 68-year-old socialite was struck by the vehicle as he crossed a street in Beverly Hills, California, today (02.09.11).
At the time of writing, he was being rushed to hospital and has a suspected broken leg.
A representative for Frederic told TMZ.com: "Zsa Zsa Gabor's husband was walking near the busy intersection of Camden Drive and Brighton Way ... when the car hit him."
He isn't believed to have been using a pedestrian crosswalk when the accident happened and police believe his "jaywalking contributed to the accident" although investigations are still ongoing.
Frederic and 94-year-old Zsa Zsa, who has been in ill health for months, celebrated their 25th wedding anniversary in August with a party at their Los Angeles home.
The bash was attended by 100 guests and even though the ailing screen legend was unable to get out of bed she watched revellers on a video screen in her room and met with around 20 friends, including legendary music producer Quincy Jones.
