Selena Gomez is gracing the latest issue of Billboard magazine.

Inside the issue, the former Disney star revealed she underwent chemotherapy after being diagnosed with lupus.

I was diagnosed with [autoimmune disease] lupus, and I’ve been through chemotherapy. That’s what my break was really about. I could’ve had a stroke.

Unfortunately, when Selena checked into an Arizona rehad facility in January 2014 to get herself together, the tabloids had a field day with reports of addictions and mental breakdowns over her break up with Justin Bieber.

I wanted so badly to say, ‘You guys have no idea. I’m in chemotherapy. You’re a**holes.’ But I was angry I even felt the need to say that. It’s awful walking into a restaurant and having the whole room look at you, knowing what they’re saying. I locked myself away until I was confident and comfortable again.

The 23-year-old singer is back on track and exploring her womanhood in her new music.

Her latest single, “Good For You,” is a saucy little jam that even took me by surprise.

Rapper A$AP Rocky, who appears on the remix, joked about Selena shedding her good girl image.

She’s developing her sexiness. I don’t think she’s there 100 percent yet. She’s probably only f**ked Justin Bieber, if that. But honestly, she wasn’t looking for a No. 1 hit. She did it to excommunicate herself from her image. That’s brave.
