Natalie Portman looked stunning in a little black dress, perhaps sending a message to her former husband, Benjamin Millepied, after declaring their separation.

The 42-year-old Black Swan star, who is set to co-star with John Krasinski in a new film, wore the eye-catching costume during an appearance on Jimmy Kimmel Live.

Portman, a mother of two, showed off her tight physique in the tiny dress, which included a sheer black bra softly shown beneath a strapless bodice.

She completed the stunning look by pairing the garment with black open-toe high heels. According to recent reports, Portman and Millepied have split up, as she did not mention him in a Wall Street Journal article about living in Paris with her children.

Despite suspicions of Millepied’s alleged affair with a 25-year-old woman last year, both he and the Star Wars actress have kept mute about the allegations.

However, in a recent interview, Portman may have alluded to the status of her 11-year marriage. The Wall Street Journal piece was published shortly after she appeared alone on the Golden Globes red carpet, notably sans her wedding band.
