Heather Locklear: David Who?

It doesn't seem like Heather Locklear is having trouble moving on from her reported split from David Spade. In fact, the blonde beauty was all smiles as she left Mastro's steakhouse in Beverly Hills Friday night, arm in arm with a new mystery man.

According to several media reports, Heather and David called it quits last week after a rumored six-month romance. However, a source tells People magazine, "Heather is still going through a lot with Denise (Richards) and Richie. It's just too soon for her to get serious. They are still friends. It's not ugly."

Update 5:53PM ET: The mystery man has been revealed to be realtor Bill Small of Aspen, Colo. Small specializes in selling high-end, exclusive residential properties. Bill is no dummy either. Heather's arm candy is a member of the United States Supreme Court Bar association and holds a Juris Doctorate degree from Seattle University School of Law as well as a BA from the University of Maine.

Is Heather in the market for a new house or a new relationship??
