Jessie J cried "happy and scared tears" after her last show before undergoing breast cancer surgery.
The 37-year-old pop star told fans she sat in her two-year-old son Sky's room having a "needed and well-earned cry" following her performance at Capital's Summertime Ball with Barclaycard at London’s Wembley Stadium on Sunday night (15.06.25).
Jessie, who went public with her breast cancer diagnosis earlier this month, wrote on her Instagram Story: "If you ever wonder what I do after a show.
"First I went to dinner with some beautiful inspiring friends and now I've got home, showered first, oilatum cream thick on my face so I look like Mrs Doubtfire.
"While the house is dark and everyone is asleep. I've unpacked my bags, done some house chores, washed Sky's cup and put washing away.
"Now I'm sitting in the Skys room just staring at him. Having a needed a well earned cry. Happy and scared tears. This boy. My whole heart. What a special day today was. (sic)"
Jessie also shared a backstage before-and-after video montage from her Capital performance.
