They're concerned that their precious sun-kissed tots, who naturally adore the easy-going movie star, will be driven to drink after watching him lounging around the beach and having a few brews.

"Matt is rarely seen without a bottle or can of beer in his hand—he likes to unwind with friends. They surf and down beer after beer," says a tipster.
