Posted March 21, 200718 yr Girls Aloud star Nadine Coyle is to marry her Hollywood actor lover Jesse Metcalfe, the London Eye column can exclusively reveal. According to an impeccably placed source, the former Desperate Housewives heart-throb will get down on one knee and propose to his Irish singing beauty "imminently" after spending just over a year as boyfriend and girlfriend. We're told: "Nadine and Jesse are completely in love and their relationship was sealed by her trip to Los Angeles to stay with Jesse recently. "They are extremely happy together and deal with a transatlantic love affair very well and so marriage is the next step for them." That's hardly surprising. 21-year-old Nadine told us recently how smitten she is with Jesse - otherwise known as Desperate Housewives' stud gardener John Rowland, who had an affair with Wisteria Lane's resident Latino seductress, Gabrielle Solis - played by Eva Longoria. She said: "Jesse is so fit and I am so lucky. I know I am." Jesse is Nadine's first serious love since she split with her former Charlton Athletic footballer boyfriend Neil McCafferty nearly three years ago. The pair were childhood sweethearts but went their seperate ways after three years together. Both claimed to be broken-hearted at the time. Nadine and Jesse got together in February 2006 after they met at a Sydney hotel where chart-toppers Girls Aloud were staying. They immediately went on a date in the romantic Australian city, and quickly became one of the most high-profile couples in showbiz. Only two weeks ago, Ulster-born Nadine returned from LA where she was staying with Jesse. Even her parents jetted over to meet the man who will be their son-in-law. However, despite living on opposite sides of the pond, we are assured that their soon-to-be engagement will not spell the end of Britain's most popular girlband since the Spice Girls. After being massively successful contributors to Comic Relief on Friday, they are now in the studio together working on a new album before beginning their gruelling rehearsals for their forthcoming tour. And, yes, Sarah Harding will be involved. Contrary to silly reports that she is to go it alone, she cites a one-off karaoke singsong with Chris Moyles as no reason to go solo.
