I am going to give an answer to the question about Castle star... SK. However, her business is her business and it should remain as such. I will say this, side shoots cover a lot, but not everything, and a post pregnancy belly is easy to detect by any women worth her own salt! So.. can we please... let other peoples personal lives be just that - personal. I like her as an actor, anything else doesn't concern me.
Ok. Watch the latest episode of Castle (Recoil), and look, at the end when Stana and the senator walk outside, pause it and look at her belly. Her button looks to be sticking out but that could be the shirt and she is getting a little stomach. I don't now about you, but, I think there's something. Other than that, I am probably wrong.
