Jason Momoa 'So Freaking Stoked' Stepdaughter Zoe Kravitz Landed Catwoman Role
'Batman Returns' Stars -- Then & Now

"I'm so proud of u zozo bear," writes the proud stepfather.

Aquaman's real life stepdaughter just joined him in the DC family and he couldn't be more excited.

Jason Momoa's stepdaughter Zoe Kravitz -- daughter of Momoa's wife Lisa Bonet and her ex Lenny Kravitz -- was cast as Catwoman opposite Robert Pattinson in Matt Reeves' upcoming "The Batman" on Monday -- and Momoa was among the many celebrating her new gig on social media.

Sharing a photo of the two of them together, he captioned the photo, "I'm so proud of u zozo bear. On and off screen OHANA. DC WB ohana Lola and Wolfies big sister is CAT WOMAN😍😍😍 Unbelievable so freaking stoked. Your going to have so much fun Aloha P bear."

Lola and Wolf are Momoa's two kids with Bonet.

Kravitz will follow in the footsteps of a long line of luminaries taking on the cinematic role including Michelle Pfieffer, Halle Berry and Anne Hathaway. Julie Newmar and Eartha Kitt clawed their way into pop culture history playing the iconic heroine on the small screen.

And Zoe is no stranger to the superhero genre as she starred in "X-Men: First Class" and voiced, wait for it, Catwoman in "The Lego Batman Movie". Reeves confirmed the news on his Twitter account with a simple GIF of Kravitz saying "hello" and social media went wild.

Kravitz's casting may come as a win for diversity in Hollywood as well, as she once recalled the time she was too "urban" for a role in 2012's "The Dark Knight Rises."

"In the last Batman movie, they told me that I couldn't get an audition for a small role they were casting because they weren't 'going urban,'" she told Nylon is 2015. "It was like, 'What does that have to do with anything?' I have to play the role like, 'Yo, what's up, Batman? What's going on wit chu?'"

Pre-production on "The Batman" is expected to start this summer.
