From Ms. Portman to Mrs. Kennedy.

Natalie Portman attended the Toronto International Film Festival screening of Jackie Sunday night, continuing her glamorous turn in Canada.

The actress, 35, kept her growing baby bump under wraps in a light green sheer dress with floral appliqués and let her light brown hair hang in loose, romantic waves.

Portman portrays Jacqueline Kennedy Onassis in the drama, which follows the former first lady in the immediate aftermath of John F. Kennedy‘s 1963 assassination. Costar Peter Sarsgaard, who was also in attendance at the festival, plays the President’s brother, Robert F. Kennedy.

The film stirred up buzz last week when it premiered at the Venice Film Festival. Portman has already scored high praise for her turn as the style icon, with many dubbing her an award contender for having a key grasp on the late Kennedy Onassis’ mannerisms and voice.

Of taking the role, Portman told reporters that she was terrified.

“I never really thought of myself as a great imitator … I was just trying to get to something that people could get past and believe I was Jackie, and then you always have yourself in there too, inevitably,” she explained.

It’s been a big week at TIFF for Portman, who debuted her baby bump while stepping out for another film, Planetarium, in Venice on Thursday. She and husband Benjamin Millepied are also parents to 5-year-old son Aleph.

Planetarium also debuted at the Toronto festival Saturday. In the drama, Portman and Lily-Rose Depp play American spiritualists Laura and Kate Barlow, respectively, in 1930s Paris. Their supernatural powers attract the attention of a powerful French film producer, who enlists the occultists for a new film project.
