Selena Gomez revealed that the real reason she took a break from singing in 2014 is that she had to undergo chemotherapy after getting diagnosed with lupus. A lot of people had speculated that she canceled part of her tour and went to rehab for some kind of drug abuse, and those people probably feel like real jerks right about now. The pop singer told Billboard about her illness and what's actually been going on:

“I was diagnosed with lupus, and I’ve been through chemotherapy. That’s what my break was really about. I could’ve had a stroke," Gomez says of her time spent out of the spotlight, which gossip-mongers took as fodder for addiction rumors. “I wanted so badly to say, ‘You guys have no idea. I’m in chemotherapy. You’re assholes.' I locked myself away until I was confident and comfortable again.”
