N-DUBZ singer Tulisa Contostavlos has reportedly ended her engagement to DJ Adam Bailey.
She reportedly decided not to marry Bailey after a violent incident in north London last year.
The Sun newspaper reports that Bailey is currently awaiting trial for GBH with intent and dangerous driving, although he denies the charges.
A source said: "Tulisa isn't speaking to him. She's trying to concentrate on work so she doesn't want any contact with him until she's made her mind up about everything.
N-Dubz are currently recording the follow-up to last year's debut album Uncle B.
