It was a family affair for newly pregnant Hilary Duff as she showed off her tiny baby bump during a sushi lunch date with her husband and sister and Breaking Celebrity News has the photos.

The mom-to-be and her hockey playing hubby, Mike Comrie, had a lot to smile about as they celebrated their one-year anniversary alongside news they are set to be parents.

The pair - who were joined by Haylie Duff and her boyfriend Nick Zano - dressed down for their afternoon outing in Toluca Lake, but Hilary's tiny tummy was just about visible.
