Chris Pratt and Anna Faris have long been one of Hollywood's most adorable couples, but the addition of their two-year-old son, Jack, has raised the cute factor even more.

The couple took little Jack to the Travel Town Museum in Los Angeles on Sunday and spent the day playing with the trains.

It made sense that 35-year-old Chris and 38-year-old Anna would have smiles throughout such a nice day.

The trio dressed warmly for the cool LA weather, sporting jackets and denim.

In Chris' case, this meant a Grateful Dead T-shirt worn underneath a grey-blue fleece jacket.

Loose blue jeans, sensible brown shoes, and a camouflage baseball cap with a red insignia completed the look for the Guardians Of The Galaxy star.

Chris also looked to be in the early stages of growing out a beard, something that made sense after he wrapped production on the final Parks And Recreation season during the previous week.

Anna, meanwhile, kept her puffy ski coat zipped throughout the day, hiding whatever shirt she wore underneath the shiny black fabric.

Well-worn blue jeans and low black boots completed the practical outfit that was accessorized with a light brown day-pack instead of a purse.

Her white-blonde hair hung straight and loose, and she covered her eyes with sunglasses.

As for little Jack, the toddler shared in his mother's choice for straight, blond hair and sunglasses, although the boy went with a dark denim jacket and khaki trousers.

The couple met on the Los Angeles set of Take Me Home Tonight, despite having grown up in Washington State towns located just a few miles apart.
