Jack Wagner Surfaces in L.A. After Blowout Fight with Heather

A smiling Jack Wagner left a gym this morning as a photog asked about his blowout fight with Heather Locklear ... but Jack wasn't talking.

It's the first time we've seen Wagner since the fight in December -- a fight that got so bad the cops were called.  As we first reported, both Jack and Heather have a date with prosecutors in a few weeks, to determine if the matter should be dropped or if misdemeanor battery charges should be filed.

The photog from the agency that shot the video asked if he thought Heather needed professional help.  We know her family thinks she does, but so far Heather is ensconced at home with no intention of seeking treatment.
