Earlier today, at a press screening, executive producer Marc Guggenheim revealed that Arrow star Katie Cassidy will make an Earth-2 guest appearance on The Flash later this season.

However, this Laurel Lance won't be the attorney-turned-masked vigilante we've known as the Black Canary. On this alternate Earth, she is known as Black Siren.

In DC Comics canon, Black Siren is Donna Nance as is based on the Golden Age version of Black Canary. She's the only female member of the Justice Guild of America, and when she isn't fighting crime, she enjoys baking, cooking, and cleaning for her male team members.
