Prepare to be very jealous of Amy Adams' 5-year-old daughter.

The Batman v Superman: Dawn of Justice star revealed that Aviana has a serious crush on mom's co-star, Henry Cavill. "She met him when she was a year and a half," Adams told ET of shooting Man of Steel. "And the first thing she did-- She hates that I tell this story. She touched his booty when he wasn't looking."

"She just reached out and he was like, 'Hmm. Your daughter?' And I'm like, 'Yep,'" the 41-year-old actress recalled with a laugh. "He's like, 'Do you train her to do that?'"

Aviana is a little less enthusiastic when it comes to her mom's role in the movie: Lois Lane.

"She was really focused on Superman for a long time and now she's starting to be curious about Lois," Adams explained. "She just started asking questions. [...] 'So, what work do you do with Henry?' and I'm like, 'Well, he's Superman' and 'Who are you with him?' I'm like, 'I'm his girlfriend.'"

"She just was like--" Adams deadpans. "She was not impressed."

Meanwhile, Gal Gadot, who joins the superhero verse as Wonder Woman, got to use her real-life experience as an Israeli soldier in the film -- and it's sure to impress her own daughter, 4-year-old Alma.

"I was ready. This is the role of my dreams," Gadot said. "Ever since I became an actress, I always said that I wanted to show the stronger side of women. Little did I know that, soon after, I would land this magnificent role."
