The upcoming Arrowverse crossover "Crisis on Infinite Earths" has fans excited for multiple reasons. On top of being the biggest crossover yet by involving characters from Arrow, The Flash, Supergirl, DC's Legends of Tomorrow, Batwoman and Black Lightning, it will also feature the return of plenty of fan-favorite actors from DC history. Not only will Burt Ward, Kevin Conroy and Lynda Carter be involved but also Smallville's Tom Welling and Erica Durance, who will reprise their popular roles as Clark Kent and Lois Lane, respectively.

With shooting for the ambitious crossover underway, we've already seen Durance join the set of Batwoman, as well as a meeting between Tyler Hoechlin and Welling's Clark Kents. Now, we also have our first encounter between two Loises.

On Instagram, Durance shared a new behind-the-scenes photo of herself and Tulloch, the Arrowverse's version of Lois Lane. "Had so much fun with this Gal last week," the actor wrote. "What a badass."

While we don't yet know the circumstance that will bring these two together, it seemingly confirms that "Crisis on Infinite Earths" will, in fact, have these two versions of the Daily Planet's famous intrepid reporter cross over.
