Scarlett Johansson is going two-for-two in her personal life.

"The Avengers: Age of Ultron" star is certainly still in her honeymoon phase -- having secretly married Romain Dauriac in October after being engaged for a year -- and she's also relishing in her newest role as a mommy.

Speaking to Barbara Walters for her annual "The 10 Most Fascinating People of 2014" special, Scarlett said her life now is "wonderful."

"It's very, very magical -- and exhausting," she said.

And, she's really wrapping her arms around "the whole bit" of mothering, she said, including diaper duty and late-night feeding sessions.

"I'm nursing and I love it," she said, adding, "It's the best way to get back in shape."
