Blue singer Duncan James has dumped Nikki Grahame, according to a report.
James started seeing the Big Brother 7 star after the collapse of her relationship with co-contestant Pete Bennett, The People has reported.
However, he has apparently been put off by Grahame's infamous strops.
"Duncan thought Nikki was gorgeous but he couldn't cope with her erratic temper," revealed a source. "She would throw too many strops and was way too emotionally unbalanced for him.
"He thought he'd give her the benefit of the doubt and just get to know her... but he didn't think she'd be as crazy in real life as she was on Big Brother. Duncan's just a young guy who wants a bit of fun and he felt it was all way too heavy being with Nikki."
