After debuting her baby bump on the red carpet at the Venice International Film Festival, Natalie Portman kept it covered up when she arrived at Los Angeles International Airport on Monday afternoon.

We had a feeling the Oscar winner was pregnant again, and at the premiere of Planetarium last week she proudly showed off her bump under a gorgeous white gown. Though she didn't comment on it, a source confirmed to Us Weekly that the actress and husband Benjamin Millepied are in fact expecting their second child together.

Portman and Millepied met on the set of Black Swan in 2010 and in 2011 they welcomed son Aleph. In 2012 the duo got married.
