Jessie J promises to ‘beat' cancer and return with ‘more music'

Jessie J just made a promise to her fans.

The English singer assured her audience at the final show she performed before undergoing surgery for breast cancer that she would “beat” the disorder.

“I've always been an open book. Today, this show is my last show before I go to beat breast cancer,” she told the crowd.

The Bang Bang crooner continued, "So, it's so special to me you have no idea. I feel so proud to be from the UK, to be an honest person and say how you feel.”

"This is my last show before go treatment and all the things It's the most special thing and I'm so grateful for this life, for you guys, for my career, to my, my son. My partner, my parents. My family, my band, my crew. We are so lucky, we have so much to live for, so much joy ... There is so much to do,” she added.

Jessie J then introduced her track, Living My Best Life, saying: "This song is the soundtrack for myself.”

"This is hands down one of the favourite songs I have written and it's called Living My Best Life. It should have been called living my breast life...” she hilariously added.

Becoming visibly emotional, the 37-year-old artist stated, "It wasn't something I'd planned, but yeah. I’m getting to keep my nipples, that’s good. It’s a weird topic and a weird situation.”

"I am going to disappear for a bit after Summertime Ball to have my surgery, and I will come back with massive t*ts and more music,” she promised.

Jessie J opened up about her breast cancer diagnosis earlier this month, revealing she is battling an "early" form of it and would be undergoing surgery soon.
