Girls Aloud star Nadine Coyle and her Desperate Housewives actor boyfriend Jesse Metcalfe have been seen looking at property in Los Angeles, sparking further speculation the Irish singer will abandon the UK for good. Metcalfe recently confessed he wants the LOVE MACHINE beauty to settle down in LA with him and start a family. But while Coyle is considering the life-changing move - which may put the British girl band in jeopardy - bandmate SARAH HARDING is at least persuading her own Hollywood hunk Stephen Dorff to come to London instead. A pal of Harding tells British newspaper The Sun, "Stephen is desperate to come to London to see Sarah. "She has spent almost every day with him (in Hollywood) but is due for work so he promised to come here with her."
