Jessie J is embracing both strength and vulnerability as she prepares to undergo breast cancer surgery. The 37-year-old singer, who recently revealed her diagnosis, performed her final show before treatment at Capital’s Summertime Ball at Wembley Stadium — a moment she called “so special.”

Posting to Instagram, Jessie shared that she cried “happy and scared tears” after the performance, spending the evening quietly with her two-year-old son, Sky. “This boy. My whole heart,” she wrote.

During her emotional set, Jessie told the 75,000-strong crowd, “This is my last show before I go to beat breast cancer!” Vowing to face the battle head-on, she thanked her family, team, and fans.

She later opened up about the rollercoaster of her diagnosis — from panic attacks to peace — reminding followers that “holding it in won’t make it go away.”

Jessie and her partner, Chanan Colman, are focused on love, healing, and motherhood in this next chapter.
