It appears the Good Charlotte rocker recently invited the Hollywood actress to his hometown near Annapolis, Md.
E! News can confirm the twosome even stopped by Kentmorr Restaurant for a friendly meal.
"It was pretty cool," owner Tammy Harper told E! News of their visit on Aug. 10. "You have Cameron Diaz here and it's like a walking amusement park…I'm just trying to let them have a nice quiet dinner, enjoy themselves and the sunset."
The couple savored the restaurant's specialty hard-shell crabs topped with Old Bay.
