The British Daily Mail newspaper said the "Pretty Woman" star has been traveling throughout the Italian capital on a Vespa motor scooter with Moder, who is also working on the set of the new film "Duplicity."

The film follows two corporate spies, played by Roberts and British actor Clive Owen. Moder is a cameraman on the cinematic endeavor.

"Duplicity" also marks the first film for the 40-year-old actress since she gave birth to her third child, the Mail said.

The newspaper said becoming a mother has been an eye-opening experience for Roberts, who said during an interview that motherhood has helped her reorganize her priorities.

"I appreciate life more. I don't feel like I have to be constantly striving," the actress said.
