moorekutcher102710_01_X12307.jpgDemi Moore and Ashton Kutcher continued to work on their troubled marriage with a private 4-hour Kabbalah counseling session at a rabbi's home Saturday afternoon.

A photographer who spotted the couple heading into the session tells X17online exclusively:

    "The both looked nervous. Ashton was smoking and Demi was skinnier than ever. It's sad because it looks like she hasn't been eating."

This private counseling session took place just days after moving trucks were spotted at the couple's posh gated community in LA.

The photographer adds:

    "When they finally came out after four hours, they were both just totally serious — no smiles, no talking — they just got in the car and went straight home."

The Two and A Half Men star allegedly hooked up with Sara Leal during a weekend trip to San Diego. For now, the couple has yet to publicly confirm a split, much less an impending divorce.
