Ashton Kutcher is flaunting a new woman and sources say he hooked up with her prior to splitting from wife Demi Moore last month. The actor, 33, spent Christmas in Italy with screenwriter Lorene Scafaria who, until recently, was dating The OC actor Adam Brody. In exclusive Us Weekly photos, the duo were snapped checking out the sights in Italy, including the famous Leaning Tower of Pisa over the Christmas holiday. During their private sojourn, the couple tooled around in a Porsche Carrera Sports 2011 and holed up at a private pad. During a romantic lunch at Pizzeria Trattoria Toscana in Pisa on Christmas Eve, they "held hands," witness Alex Thorpe tells Us. "They shared spaghetti, and he paid." Meanwhile Moore, 49, kept a low-profile, spending her holidays with family including daughter Rumer Willis in Parrot Cay. "She's doing really well," a source tells Us. "[She's] waiting for all of her stuff to come out in the new year [including] her Lifetime show that she's executive producing." Despite 33-year-old Scafaria's romance with Brody and Kutcher's marriage to Moore, a source says they have been stoking a romance since meeting in February, when Kutcher tried out for a film she wrote."Ashton started seeing her while each was in a relationship," says a source. Reps for both Kutcher and Scafaria deny this and tell Us. "They're just friends." And it wasn't the first field trip for the duo --- on Dec. 9 and 10, they cozied up at Yellowstone Club ski resort (snowboarding and playing shuffleboard) in Montana. Kutcher's ex Moore, of course, announced their plans to divorce in late November following his revealed affair with a different woman, 22-year-old Sara Leal in September.
