Selena Gomez Has Lupus (So Says Grandpa)

Selena Gomez is quietly fighting lupus, according to the singer/actress’ paternal grandfather.

Lupus is an autoimmune disease in which the body’s immune system attacks healthy tissue. The one-time star of Disney’s Wizards of Waverly Place was diagnosed with the potentially life-threatening condition “a couple of years ago,” Ricardo Gomez told Hello! magazine Thursday.

“She’s in treatment. She’s getting along pretty good.”

The “Who Says?” songstress, 21, was briefly admitted to rehab (for alcohol/prescription drug addiction or exhaustion — depending on who’s telling the story) in January. Mr. Gomez says Selena’s alleged struggles with addiction, her grueling work schedule and her on-again/off-again romance with crooner bad boy Justin Bieber have made her lupus less manageable.

“What worries (us) more is that she doesn’t know how to say no. She won’t take time for herself to relax, to eat well.”

He added:

“We just saw in some newspaper that she was doing drugs. I called her and said, ‘[You] need to watch out…’ She was working a lot. She was exhausted. She hardly takes some time out…The doctor was telling her she needs to take some time out It’s just too much pressure what she’s going through. It’s just too much! She doesn’t have a single day’s break…Everyone was telling her, even her agent and the doctor, ‘Selena take some time to yourself!'”

Selena’s work as a UNICEF ambassador recently took her on a mission to Nepal. She arrived back in the U.S. on Thursday.
