Pop star Jessica Simpson has shocked fans by confirming her romance with rocker John Mayer is over. After Simpson attended the Cannes Film Festival solo earlier this week (beg14May07), rumours were rife that the couple's nine-month romance had cooled. And now US news show Extra is reporting the split is official. Simpson, 26, and Mayer, 29, spent months refusing to talk about romance rumours but confirmed they were an item during a romantic March (07) break in Rome, Italy, where they kissed and held hands. The couple was last seen together at the Costume Institute Gala in New York on 7 May (07). The split news comes just days after Simpson's manager father Joe announced he approved of his daughter's new beau, stating, "I love him; he's got great music... and he's a legend already."
