The Sun reports Girls Aloud star Nadine Coyle and her actor boyfriend Jesse Metcalfe have mutually agreed to end their 8-month romance. “They had a tearful phone conversation at the start of the week and called it a day,” a friend revealed. “They have both been flying to spend a few days with each other between work commitments. But it has not been easy. Nadine is enjoying the best run of success that Girls Aloud have had. Their greatest hits album just went to #1. And they have signed up for a massive tour and new studio album next year. So her work diary is filled up to 2008 and Jesse’s film career has really taken off. It wasn’t what either of them wanted – but they felt they had no other option. Work has had to come first.” Meanwhile, Nadine’s bandmate Sarah Harding has found a new boyfriend, an unnamed man referred only as “an unkempt journalist”.
