The 27-year-old suffered a stroke at 18 and has an existing heart condition but has remained silent on the cause of her latest incident.

In a post to her Instagram account, J confirmed she had an operation but said it was not to do with her heart or her voice.

Channel 9 have also refused to give details of her illness.

“I had an operation yesterday so need to rest,” she said in a comment.

“I won’t be saying what for so PLEASE don’t keep asking me or harassing my close ones on here or anywhere for information. It’s personal and I know you can ­respect that.

“And for the record it’s not my heart or my voice. My heart and voice are FINE,” she wrote.

The pop star said hospitals had been her “secret second home” her entire life.

While she has been silent on the cause of her latest hospital visit, J has kept worried fans up to date on her recovery with detailed posts to social media.

“I’m out of hospital. Still very fragile but much better,” she posted to Instagram.

After being forced to cancel a series of concerts in Europe, J looks to be back on track to continue touring her latest release Sweet Talker with upcoming dates in Lebanon and Finland.

The singer has been juggling a hectic touring schedule with her first role on The Voice Australia.

Her upfront attitude and insistence on playing by her own rules has led to plenty of ­on-screen tension with her fellow coach Delta Goodrem.

In the latest confrontation, Goodrem told J “I’m going to kill you,” after convincing a contestant to choose Benji Madden as his coach.

According to viewers, and coaches it’s a tired but longstanding trend of pitting women against each other for publicity.

“I’m so a believer in girls supporting girls,” Delta Goodrem said

The singer queried why nobody asked Ricky Martin and the Madden brothers if they don’t like each other.

The public have been making their displeasure of the female catfighting clear, with many stating they believe it’s a marketing ploy.
