Scarlett Johansson welcomed her first child, a baby daughter called Rose Dorothy, with then-fiancé Romain Dauriac this past September, and although she is still getting used to motherhood, the 30 year-old actress recently admitted she is finding it "exhausting."

While being interviewed on the ABC annual special, Barbara Walters' 10 Most Fascinating of 2014, Johansson once again gushed about being a first-time mother, and revealed how she is planning to lose her post-pregnancy weight.

"It's wonderful. It's very, very magical - and exhausting," she said of motherhood to Walters. "The love is just unbelievable. It's very overwhelming."

This past March, the happy couple confirmed they were expecting their first child together, and on September 4th the 'Avengers' star gave birth in New York City.

The Hollywood actress, who secretly tied the knot with Dauriac in Montana at the start of October, also revealed how she doesn't mind doing the more tedious tasks such as changing diapers and breastfeeding, which is also helping her lose weight.

"[I do] the whole bit. I'm nursing and I love it," she said. "It's the best way to get back in shape."

Johansson, who first began dating the French journalist in November 2012, echoed these comments while speaking the latest issue of Germany's Gala magazine, in which she said motherhood is "exhausting in the most wonderful way. I never thought how much sleeping through the night would mean to me."

Walters' ABC special, The 10 Most Fascinating People of 2014, will air on Sunday at 9pm.
