Lady Gaga "Borderline Positive" for Lupus
A subdued Lady Gaga confirmed for CNN's Larry King Tuesday night that Lupus runs in her family, and she's tested "borderline positive" for it.
During the rare television interview, the usually boisterous, provocative and outrageous singer - one of the world's most popular and considered by many to be the leading lady of pop -- addressed Internet rumors that she has the autoimmune disease.
She told King, "Lupus is in my family and it is genetic. My mother told me the other day that my fans were quite worried about me because I did talk about the fact that I was tested for Lupus."
"And ah, the truth is, I don't show any signs, ah, any symptoms of Lupus. But I have tested borderline positive for the disease. So, as of right now, I do not have it, but I have to take good care of myself."
It's believed Lupus is hereditary and is what killed Gaga's aunt in 1976, reports CBS News Correspondent Elaine Quijano.
Lupus affects roughly one-and-a-half million Americans, mostly women. It causes the body's immune system to become hyperactive and attack normal, healthy tissue.
Gaga's flamboyant look and string of hit singles have her career on fire. Her 2008 album "The Fame" earned her two Grammys. And the video for "Bad Romance" is the most-watched clip ever on YouTube.
On "The Early Show" Wednesday, CBS News Medical Correspondent Dr. Jennifer Ashton discussed Lupus with co-anchor Julie Chen:
