The couple was leaving a Los Angeles restaurant when a photographer tried to snap photos of them. Hewitt and Hallisay allegedly asked the photographer to stop, but he continued. Hallisay then got into an altercation with the paparazzo, who claims his camera then hit him in the face.
The photographer later filed a battery report against Hallisay, and police are investigating the confrontation.
Hewitt, 34, is expecting the couple's first child in November.
