We spotted Wedding Crashers star Isla Fisher and her funnyman fiance Sacha Baron Cohen taking a Sunday afternoon walk in the Hollywood Hills. Can you believe she's nine months along already? We can! In fact, we have Naomi Watts flashbacks every time we see her! (Remember when we caught them out and about together?)
