Selena Gomez says she is taking some time off to deal with panic attacks, anxiety and depression.
In a statement, the singer revealed her mental health problems are a side effect of her lupus diagnosis.
She revealed last year that she was being treated for the disease which affects the body’s immune system.
The 24-year-old says she now needs time out to face her health issues “head on.”
Speaking to People magazine she said: “As many of you know, around a year ago I revealed that I have Lupus, an illness that can affect people in different ways.
“I’ve discovered that anxiety, panic attacks and depression can be side effects of Lupus, which can present their own challenges.”
“I want to be proactive and focus on maintaining my health and happiness and have decided that the best way forward is to take some time off.”

She thanked all her fans for their support: “You know how special you are to me, but … I am doing everything possible to be my best.
“I know I am not alone by sharing this. I hope others will be encouraged to address their own issues.”
It is not clear how much time Selena Gomez will be taking off. She is in the middle of her Revival world tour, with several upcoming dates.
She is due to come to the UK in October.
There has been no official notification that the remaining dates have been cancelled, although it is widely expected they will be.
She was forced to cancel the end of a previous tour in 2013, prior to her lupus diagnosis. She went to a treatment facility in 2014 and had chemotherapy.
Two weeks ago, the singer got into an online argument with ex-boyfriend Justin Bieber.
It followed his rant at fans who’d been posting negative comments about pictures of him with girlfriend Sofia Richie.
Under an image of the couple she wrote: “If you can’t handle the hate then stop posting pictures of your girlfriend lol – it should be special between you two only.
“Don’t be mad at your fans. They love you.”
