Scarlett Johansson says that filming sex scenes is a "liberating" experience. The 30-year-old actress, who has recently become a mother, says that you have to put aside your "judgement" while acting out a passionate scene, in front of the camera.

"It's sort of liberating. Its challenging, but you've just got to stay in the moment," she said to Barbara Walters of ABC News. Scarlett also spoke about motherhood and how her life has changed post giving birth to husband Roman Duariac's baby. She reportedly finds the whole new phase "overwhelming."

The "Don Jon" actress has not hired any nanny and is said to be taking care of the new-born all by herself. The actress is currently breast-feeding her daughter and is enjoying every bit of it. She even thinks that nursing is the best way to shed the pregnancy weight.
