Jessie J posts video revealing mystery surgery

In a split, slo-mo, video posted on Instagram, Jessie J revealed a before and after shot of a mystery surgical procedure she recently underwent.

One part of the video shows the Sweet Talker hitmaker preparing for her surgery - which she has decided to keep private - by putting on pre-surgery socks, you know the same you wear before you go on a long haul flight.

The other part of the video showed Jessie lying in a hospital bed, looking drained but giving a thumbs-up to the camera.

In the caption of the video she explained that she would be going offline for a while. She also wrote: "I don't often share personal stuff (especially about my health) anymore. I just get on with it secretly but I wanted to share with you before someone else might and it gets twisted and exaggerated into something different or worse.

"Just know I am ok as I say in the video on the right. I had an operation yesterday so need to rest. 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. Its personal and I know you can respect that.

"I just wanted to explain to my fans why I may go AWOL for a minute. Love, prayers and well wishes is all I need."

"There is always someone worse off than us and in moments like this I pray for you all," added the star.

"Hospitals have been my secret second home my whole life and they never get nice to be in. But they can inspire a great song. Trying to see the positive in everything."

The OZ Voice judge was quick to add that the surgery was not related to her voice or her heart - as a child Jessie was diagnosed with a heart defect.

And ended the post by saying: "Night gown could be good for the Voice live shows look too, right? No? Too Much? lol Peace out for a minute people."

The day before posting about her surgery Jessie posted the below picture with the caption "it's OK not to be OK".

Well, we certainly hope you're OK and get well soon!
