Natalie Portman gave birth to child number two, Amalia, on February 22. But apparently, the "Black Swan" actress had filmed a music video for James Blake's single, "My Willing Heart", just days before her due date. The artsy video was premiered on March 20.

In the black-and-white clip, Portman swims underwater. She gracefully moves and shows her pregnant figure in the water. She also strips down to lingerie while sitting on the bed, cradling and caressing her baby bump. In a close-up shot, it can be seen baby Amalia kicks from inside her mommy's belly. At one point in the video, Portman plays with a child who is reportedly Aleph, her first child with husband Benjamin Millepied.

The lyrics of the track seem to match the visuals of pregnant woman who's ready to give birth to her baby. "When I see my willing heart, how will I know?" Blake sings in the chorus. "How will I walk slow? How will I know?"

"My Willing Heart" is one of the tracks off Blake's 2016 album, "The Colour in Anything". Although the album was released in May, "My Willing Heart" is the first track to get a music video.

The Anna Rose Holmer-directed video was filmed in Los Angeles just days before Portman announced that she would miss this year's Academy Awards due to her pregnancy. She was nominated for Best Actress for "Jackie", but lost to "La La Land" lead actress Emma Stone.

Prior to this, the actress also showcased her burgeoning belly in a photo shoot for Vanity Fair last January where she cradled her baby bump with only white sheet draped around her body.
