Singer Jessie J has revealed she was hospitalized with an infection after undergoing surgery for breast cancer earlier this summer.

"Having to change the plans for my career for this year has been frustrating," the "Bang Bang" singer said of her health issues on Sunday.

Jessie J has been rushed back to hospital weeks after her breast cancer surgery, suffering from an infection and fluid on her lungs. Last month, the Bang Bang hitmaker shared that her cancer had not spread after a shock early diagnosis halted her return to the spotlight.

A mass shooting in downtown Los Angeles has left two people dead and six injured in the early hours of Monday following the Hard Summer music festival, the Los Angeles Police Department confirmed to The Hollywood Reporter.
