John Blanchette on Sunday described Gabor's health situation following her surgery a day earlier as "very sad."
Blanchette told the Los Angeles Times the 93-year-old Gabor asked for a priest and he administered the sacrament Sunday morning.
The paper reported that Gabor was being fed through a tube, but that doctors hoped to get her to eat without it Monday.
Gabor underwent surgery for the removal of the clots from her upper body. She had broken her hip July 17, had hip replacement surgery and had just returned home from the hospital Wednesday.
