Pop star Jessie J has shared an open and honest video after undergoing surgery just weeks after her breast cancer diagnosis.

Jessica Cornish, also known as the singer behind “Bang Bang,” shared with her fans that she is now back home and will be taking time to recuperate while awaiting her test results.

“This post is some of the honest lows and highs of the last 48 hours,” the British singer, 37, wrote on Instagram Monday.

“I will always show the good and hard bits of any journey I go through. Grateful to my doctor / surgeon and all the nurses who cared for me and all my family / friends who came to visit,” the “Price Tag” singer told her 14 million followers on the platform.

The singer’s post included a series of photos, including one of her in the hospital bed, as well as pics of her 2-year-old son Sky and boyfriend Channan Safir Colman.

In one clip, the “Domino” singer explained to her son that the surgery involves her blood being drained from her breasts.

“So the water and the blood comes out of mommy’s booby and comes out of the tube and into the bottle,” she tells the youngster in the video.

Another image shows Colman plant a kiss on her forehead as she awaited surgery.

“Still hugging everyone going through something tough right now. We all got this! 🫂🫀🔋,” she concluded her post.

In her initial health post earlier this month, the singer told fans she had learned of her diagnosis three months ago, just before her single “No Secrets” was released in late April.

The Grammy nominee even pointed out the irony of her health battle.

“To get diagnosed with this, as I’m putting out a song called ‘No Secrets’ right before a song called ‘Living My Best Life,’ which was all pre-planned before I found out about this. I mean, you can’t make it up.”

Following her performance at the Summertime Ball in London on June 15, the singer bid her fans a temporary farewell, saying she is going to “disappear for a bit.”
