According to our baby name finder, Orla is of Irish origin, meaning 'golden'. Former Coronation Street actress Katherine announced her pregnancy in September, tweeting: "Ryan & I are overjoyed to announce that we are expecting a baby! Feeling very blessed!"
Katherine and Ryan married in August 2013 after three years together. The couple eloped and got hitched in Vegas at the Little Church of the West, saying it was 'just about the two of us'.
Katherine found fame playing Becky McDonald in Coronation Street before quitting and starring in the hit drama Mr Selfridge.
Congratulations Katherine and Ryan!
