Singer Jessie J is facing an unexpected health setback as she continues to recover from breast cancer surgery. "How I spent the last 24 hours," Jessie, 37, wrote via her Instagram Stories on Sunday, August 3, sharing a photo of an IV connected to her arm. "Six weeks post-surgery, and I was back in the same ward I was after my surgery. Not expected or planned." She added, "I had, and still have, symptoms that pointed towards a blood clot on the lung. IT IS NOT A BLOOD CLOT, THANK GOD.
