If you’ve been watching the Supergirl trailer on repeat and thinking, “So…is Superman taken?” (guilty), I’ve got some bad news for you: David Corenswet is very much taken. The DC flick’s star has been married to his real-life Lois Lane, fellow actor Julia Best Warner, since March 2023—though their relationship goes all the way back to when they were teens. Love that for them.

Ofc, you may not have realized David was even off the market, as he and Julia only made their red carpet debut last year at the Superman world premiere. So! Since we know you’re curious, here’s everything you should know about Julia and her low-key relationship with David.

Julia is an actor

Before falling in love with David, Julia fell in love with acting. “I think performing was probably my first love,” she told Nerd Alert News back in 2020.

Her biggest role to date was in Netflix’s Ratched, and in December 2025, she announced her latest project: a role in Michael Cera’s directorial debut, Love Is Not the Answer.

She met David when they were just teenagers

As teens, Julia and David both attended a Pennsylvania summer theater program called Upper Darby Summer Stage (which, fun fact, was also attended by Tina Fey!). It was there that they crossed paths for the first time, as David told People during his June 2025 cover story interview.

She and David have a daughter together

According to an April 2025 profile in Time, Julia and David share a daughter who was born in 2024, though they’ve never publicly revealed her name.

Oh, and apparently, Julia found out she was expecting right before David landed his role as the Man of Steel. He told People of the timing, “She told me she was pregnant two days after I found out I was going to screen test for Superman… We had these two quite huge secrets that we just had between the two of us.”

She helped David audition for Superman

While chatting with People, David explained how his wife helped him land the iconic role. “She helped me make my first self-tape for the part, and she felt at that point that I should get the part,” he said. “I thought she was crazy, but she felt it from the beginning. So if anything, I knew that she would be even more excited than I was.”
