British pop star Jessie J went through a secret break-up last year (13) as her long-term relationship crumbled.

The Price Tag hitmaker has revealed she was in a relationship which came to an end in 2013, and she chose to keep her heartache private.

The singer has poured her emotions into a new song titled You're Lost, I'm Found, and reveals her partner struggled with intimacy issues.

She tells Britain's Event magazine, "Last year I was in a relationship for quite a long time. Not in secret, but I chose for it not to be in public. And I had to leave the relationship because I was doing my best but I wasn't being let in. I've written a song about it called You're Lost, I'm Found. It says, 'I know I'm good enough for you but you won't let me be and one day you'll discover that.'

"I wrote all that stuff on my own, very quickly. I really needed to get it all out. It felt amazing."

Earlier this year (14), Jessie J revealed she only dates men now, three years after coming out as bisexual.
