What happened to hubby lunch buddy, Josh Kelley? Just wasn't the same, was it?
Now, it looks like Katherine's back to her old ways, because she's been spotted out having lunch with mom (above) at Little Dom's in Los Feliz once again.
We hope you and mom had a lovely lunch together, Katherine! Maybe next time you can try ANOTHER new lunch companion!
How about your Knocked Up co-star Seth Rogen? When's the last time you two hung out?
