Kate Walsh is Smoking, Not Pregnant

Kate Walsh makes nice with paparazzi (she’s always smiling for them!) and heads into the photography studio at Pier 59 Studios West in Santa Monica, Calif.

We can probably shoot down those pregnant rumors down now! Kate, 39, was seen smoking a cigarette in her bathrobe between takes. Unless . . . . . . nahhhhhhh!!!!!

And the engagement party she went to in Pasadena on Saturday was apparently was for her and fiance Alex Young.

10+ pictures inside of Kate working her photo shoot magic…
