Have you been wondering which actress would be stopping by the 2018 Arrowverse crossover?

Thankfully, we now know who will take on the iconic role.

Per The Hollywood Reporter, Grimm grad, Elizabeth Tulloch has landed the coveted role, but there's no word yet on whether she will appear on all three episodes of the crossover.

If you watched Grimm online, you're probably thinking to yourself that this is some excellent casting. Tulloch brought her A-game for her performance of Juliette.

Lois will show up alongside her on-screen love interest Clark Kent aka Superman. The Man of Steel will, once again, be played by Tyler Hoechlin who has appeared in the Arrowverse multiple times already.

Not much is actually known about the crossover, save for the fact that it will introduce us to Kate Kane aka Batwoman.

She will be played by Orange is the New Black's Ruby Rose, and there is even the possibility of that new character to the Arrowverse landing a show of her own.

In a vote of confidence, The CW is pressing forward with a pilot for the proposed spin-off without fans seeing Rose in action as the character.

But what would that series be about?

"Armed with a passion for social justice and a flair for speaking her mind, Kate Kane soars onto the streets of Gotham as Batwoman, an out lesbian and highly trained street fighter primed to snuff out the failing city’s criminal resurgence," reads the official logline for the series.

"But don’t call her a hero yet. In a city desperate for a savior, Kate must overcome her own demons before embracing the call to be Gotham’s symbol of hope."

Unlike previous years, the crossover will span just three of The CW's DC series. Arrow, The Flash, and Supergirl will be featured, but DC's Legends of Tomorrow will be left out in the cold.

In a sense, this is a good move. Telling a story over four episodes with a LOT of characters is not the easiest things to do.
