Lady Gaga 'Larry King' Interview, Alejandro Music Video

In an interview on "Larry King Live," Tuesday night, Lady Gaga talked about her health, being tested for lupus, her fiercely loyal fans and the offer to work with Michael Jackson on his tour.

The 24-year-old singer admitted that she tested "borderline positive" for lupus, an autoimmune disorder.

"Lupus is in my family, and it's genetic," Gaga said. "It's funny, my mother told me the other day that my fans were quite worried because I talked about the fact that I was tested for lupus. And the truth is, I don't show any signs, any symptoms of lupus. But I have tested borderline positive for the disease. As of right now, I do not have it, but I have to take good care of myself."

The "Bad Romance" singer told Larry that she was asked to open for Michael Jackson's "This Is It" tour in London before he died.

"I don't necessarily like to talk about those very personal things that happened but I guess I can speak about it now," Gaga told the host. "We were going to open for him at the O2 and we were working on making it happen."

Gaga also showed a clip of her new music video for the song "Alejandro." Check out the videos.
