It's hard to believe Natalie Portman gave birth just one year ago.

The Oscar winner, 31, recently showed off her stunning post-baby body on the beach alongside her new husband, Benjamin Millepied (the couple tied the knot on Aug. 4) and their 14-month-old son, Aleph, on the beach at the Parrot Cay Resort in Turks and Caicos.

Their beach time may in fact be a delayed honeymoon for the "Black Swan" actress and her choreographer love; instead of jetting off to an exotic location after exchanging vows, the couple instead opted to attend a Los Angeles Philharmonic concert on the Tuesday following their nuptials.

"She has this glow about her these days," a source close to Portman recently told Us Weekly about the star's new life as a mom and wife. "There's been a change in her since the little man arrived. She and Benjamin are so content."
