Kate Walsh: Pregnant or Poor Posture?

Private Practice star Kate Walsh leaves the local gym after her hour-long pilates class on Thursday in Los Angeles, Calif.

After her work-out, Kate met up with an older mystery male for lunch at an outdoor restaurant.

If you thought she was paparazzi shy on Wednesday, smiling for photographers this time must be a complete 180! (Also maybe pulling down her shirt to cover up her belly?)

10+ pictures inside Kate possibly getting her baby bump on…
