Jessie J has revealed that she "can't ever have children".

"I was told four years ago that I can't ever have children," Jessie said, according to Metro.

"I don't tell you guys for sympathy because I'm one of millions of women and men that have gone through this and will go through this."

The 30-year-old singer went on to explain that she penned a song called Four Letter Word, from her latest album R.O.S.E, to help her process her heart-breaking situation.

"It can't be something that defines us," she continued, "but I wanted to write this song for myself in my moment of pain and sadness but also to give myself joy, to give other people something that they can listen to in that moment when it gets really hard.

"So if you've ever experienced anything with this or have seen somebody else go through it or have lost a child, then please know you're not alone in your pain and I'm thinking of you when I sing this song."

Jessie J's message comes after a 2013 interview where she had expressed her longing to have children "very soon".

Speaking with Marie Claire at the time, Jessie said: "When I turned 25, something changed in me. I see children in my future 100 per cent. Very soon."

During her heartfelt speech, supportive boyfriend Channing Tatum – who recently split with ex-wife Jenna Dewan - watched on in the crowd.

The 38-year-old actor later took to Instagram to commended his new beau, writing alongside a photo of Jessie J on stage, "This woman just poured her heart out on stage at the Royal Albert Hall. Whoever was there got to witness something special. Wow."
