Alexandra Burke has reportedly dumped her boyfriend after he was accused of cheating on her again.
The 'Bad boys' singer - who began dating England soccer player Jermain Defoe earlier this year - is said to have ended their relationship after he allegedly slept with a second woman behind her back.
A source told The Sun on Sunday newspaper: ''Alex is heartbroken but she has ended it. It's all over. They are not together any more.
''Alex thought Jermain might be the one but has now decided to move on with her life.''
Last month, Tottenham Hotspur striker Jermain is said to have cheated on Alexandra with model Laura Brown and it has now been claimed he slept with nurse Kirsty Crummey while romancing the former 'X Factor' winner.
Kirsty claims had sex with Jermain after he invited her over to his mansion in north London six weeks ago.
She recalled: ''After a few minutes we moved to a spare room. I guess he felt more comfortable there because it didn't feel so much like cheating. I didn't want to hear about Alexandra and he never mentioned her. I guessed he was with her but I didn't want to know the truth.
''I'd fallen for him and I suppose I was fooling myself we could be together.''
