Zsa Zsa Gabor was rushed to the hospital Friday morning after suffering from a “massive blood clot,” the actress’ rep told TMZ. The 93-year-old socialite reportedly complained about pain and swelling in her leg, leading to a house call from a doctor who called 911 upon discovering the clot. Gabor’s husband, Prince Frederic von Anhalt, told TMZ she had a “bad infection” in her right leg and “no blood flowing” in her left. According to the Los Angeles Times, doctors are concerned the clots could lead to a heart attack. Gabor is at UCLA Medical Center, which she was in and out of this summer after complications from hip-replacement surgery.
