Tulisa Contostavlos has opened up about her split from her N-Dubz bandmate boyfriend Fazer after suspecting him of cheating on her.
The Young singer, who is currently serving as a judge on the UK X-Factor, has discussed the break-up for the first time in her new autobiography, Honest: My Story So Far.
In the book, serialised in The Sun newspaper, Contostavlos recalls: "He started going out more while I was working and coming home later and later - I didn't have a clue where he was most of the time. We began arguing a lot.
"I found myself more jealous than I have been in any other relationship. 'Phone check' I'd randomly and regularly demand, holding out my hand. Fazer would be expected to hand me his phone so I could scan it for texts or messages from his ex or anyone else I might not approve of."
Tulisa further admitted that she used to pretend to be her boyfriend and message women of his phone in a bid to discover the truth.
She added: "I was texting stuff like: 'Ah, come on babe, you know I've got a girlfriend.' Then she'd text back: 'Well, that never stopped you before, did it?'"
The pair attempted to patch up the relationship on a holiday to the Maldives in January, but decided to part ways on their return to the UK.
