The Star Wars actress and her choreographer husband, Benjamin Millepied, welcomed their second child on February 22!
The couple, who worked together on the blockbuster movie, Black Swan, have been married since 2012 and are parents to 5-year-old Aleph.
Portman generally keeps a low profile and doesn't have any public social media accounts, but SkyNews received confirmation from her publicists that Natalie and baby Amalia are in fact happy and healthy.
Portman gave the Oscars a miss this year, even though she was nominated for the role of Jackie Kennedy in her latest movie Jackie, because she was due to give birth.
Before the public was informed that Portman was not going to attend the Academy awards, Portman made an appearance on Jimmy Kimmel Live and spoke about how she eats before events so she's not famished.
She also joked with Kimmel about going into labour at the awards. Kimmel expressed how he would be honoured to deliver her baby and how she could name her baby after him.
