It's no surprise that the 32-year-old actress has singing chops -- and though she doesn't often show them off publicly, she does go into "jukebox" mode at home with her daughter!
"I sing a lot, all day, probably much to her annoyance," Johansson told ET's Cameron Mathison on Monday, opening up about life with her 2-year-old, Rose Dorothy. "Sometimes it's songs she doesn't want to hear, so she'll just go, 'No, no, no! Not that one.' I'm like a jukebox, just press 'skip.' Next!"
The Ghost in the Shell star gushed over bonding with her baby through music, revealing that the pair even sometimes duet on Frozen's "Let It Go."
"She's got a good ear!" Johansson said. "She sings along with me."
When she's not in mommy-mode, Johansson is promoting her new film, Ghost in the Shell, out March 31. The actress was on hand to debut special new footage from the film and revealed she's only seen the trailer so far.
"I was really blown away by the opening, the shelling sequence," she said. "I saw the shelling sequence and the trailer when they premiered both of those in Tokyo. I was really excitedly there at this beautiful event that Paramount had planned. I'm, you know, cautiously optimistic, as I always am. But I love this character. I'm really into the world that [director Rupert Sanders] created, and I'm excited to see it all pieced together."
Johansson also revealed that her husband, Romain Dauriac, is already a big fan of the film -- even though he hasn't seen it yet, either!
"He loves this world," she said. "If Blade Runner continued on into the future and was this weird, dystopian reality -- that would be his ideal."
Johansson sat down with ET in New York City just one day after Golden Globe festivities concluded in Hollywood. But on Sunday night, it was mommy duty that took precedence.
"I missed the Golden Globes!" she said. "I was too busy, you know, trying to make, like, mac-and-cheese, and, 'Are we going to watch the Tinkerbell movie or Strawberry Shortcake? My world is all into that right now."
