The Pretty Woman star agreed to co-star with Clive Owen in the feature film Duplicity.
"I love Clive and we have chemistry because we have a similar spirit and energy. We had to be all serious and sexy but after the director said ‘Cut’ we would just be laughing," said Roberts.
Although the 41-year-old actress had fun on the set of her latest film, family remains her number one priority. "My life at home gives me absolute joy," explained Roberts, adding that taking care of three children is not always easy.
