Gabor was reaching for her ringing phone.
Her husband, Prince Frederic von Anhalt, called an ambulance and Gabor was taken to Ronald Reagan UCLA Medical Center in Westwood.
According to von Anhalt, the fall was "bad" and said her condition is serious.
Officials with the hospital confirmed that Gabor's family members are by her side, but did not release her official condition.
The Los Angeles City Fire Department confirms that they got a call at 7:39 p.m. They also confirmed that one female was transported.
Gabor is known for her many TV and film appearances dating back decades, including "Moulin Rouge" in 1952 and more recently in "The Naked Gun 2 1/2: The Smell of Fear" in 1991.
Gabor made headlines in 1989 when she slapped a Beverly Hills police officer when he stopped her for a traffic violation. She served three days in jail for that incident.
The actress is partially paralyzed from a 2002 car accident, which forced her to use a wheelchair.
She also reportedly had a stroke in 2005.
