Ashton Kutcher (@aplusk) tweeted this photo of him, Lorene Scafaria and a friend in Italy.

Us Weekly has published photographs of Ashton Kutcher with someone who could be his new girlfriend. The "Two and a Half Men" star, who split from wife Demi Moore in November, was spotted sightseeing in Italy with screenwriter Lorene Scafaria.

A witness, Alex Thorpe, is quoted as saying that the pair enjoyed a romantic lunch in Pisa on Christmas Eve, where they "held hands" while sharing spaghetti, which he paid for.

Scafaria was linked to "The O.C." star Adam Brody until recently, but Us Weekly's sources say that she and Kutcher have been romantically involved since February, long before his official split from Moore. (She filed for divorce from him in November following a rash of reports about his alleged infidelities.)

Representatives for both Kutcher and Scafaria denied  the story and told Us Weekly, "They're just friends."
