In Game of Thrones S8E04 when Daenerys meets with Cersei, and Tyrion says aloud that Cersei is pregnant, did anyone else other than Jamie, Tyrion, Euron and Qyburn (Cersei's Hand) know about it? I.e., is there any plausible way of Tyrion finding out about Cersei's pregnancy without her telling him?

If not, I could see this causing issues between Cersei and Euron since she only recently told him about it, so how else would Tyrion also know unless it happened much earlier?
