Back in late 2013, Selena Gomez cancelled the Australian and Asian leg of her world tour, before checking into rehab in early 2014.

But now Selena Gomez has spoken out, revealing that the actual reason for her time out of the spotlight was down to her being diagnosed with lupus – and having to undergo chemotherapy.

Speaking to Billboard magazine, Selena explained:
"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. 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."
She went on to say that at the time, the speculation surrounding her time away from the public eye made her really angry.
Selena said:
"I'm so fucking nice to everybody and everyone is so vile to me. I've been working since I was seven. I've been a UNICEF ambassador since I was 17. It's so disappointing that I've become a tabloid story."
