Katie Cassidy is 31 today; she now plays Dinah Laurel Lance/Black Siren on Arrow (with the usual crossovers to other Arrowverse series), and also stars in two upcoming movies.

I cannot imagine this is a very happy birthday for her. It's tragic that her father died so very close to her own birthday.
