James Blake featured the expectant mother in his video for "My Willing Heart," released on Monday.
In the black and white video, directed by Anna Rose Holmer, features a very pregnant Portman swimming in a pool and later caressing her baby bump.
Later, an dramatic first-person perspective shot shows her baby squirming and kicking in utero.
Portman gave birth to her daughter, Amalia, on February 22 — days after the video was shot.

Amala is the second child for the Oscar winner and her husband, dancer Benjamin Millepied. The couple also have a 5-year-old son, Aleph.
"My Willing Heart" comes off Blake's critically acclaimed 2016 album, "The Colour in Anything."
The British singer/songwriter is best known for experimenting with different styles of music, including electronic and rap.
