Paris has a career as a singer in her own right and it is believed that she and Justin met when he worked started working with her band before he collaborated with her on her track 'Blue Moon'.

But the 'hit your knees' singer has previously been linked to the likes of Cara Delevigne and recently admitted that she always thought she would end up marrying a woman.

She said: "[I] thought I'd end up marrying a chick. I've dated more women than men. Been with more chicks."

Prior to her relationship with Justin, Paris dated bandmate Gabriel Glenn noted when it all came to an end it had been the "deepest" love she had ever felt.

Speaking on 'Red Table Talk', she explained: "It was the deepest I ever loved someone, it was the most intense I've felt so far and the most intense betrayal I felt so far and experienced.

'It's definitely closed me off to that, I'm very careful with who I spend time with now and very guarded and trying to protect myself."
