Ashlee Simpson approves of big sister Jessica's new beau John Mayer. According to People magazine, 22-year-old Ashlee thinks the 29-year-old singer-songwriter and 26-year-old Jess are a perfect match. A source told the magazine, "She thinks he is great for her. More importantly, Jess is happy." Jessica and John recently returned from a vacation in Rome, and seem to be more in love than ever. Jess, John and Ashlee were recently spotted dining out together at the Parc restaurant. The Dukes of Hazzard actress and singer Jessica's clearly enjoying a quieter, more low-key life with Mayer, very different to the mediafest that was her marriage to ex-husband Nick Lachey. |
