NEW: First Look At Natalie Portman Post-Nuptials [PHOTOS]

Natalie Portman was seen out today (August 10th) for the first time since marrying Benjamin Millipied last weekend in Big Sur.  The Oscar winner rocked her wedding band and engagement ring in Beverly Hills as she left an office building.

Portman wore Rodarte to marry Millipied, whom she met on the set of Black Swan (Rodarte designed the costumes for this film).  According to People Magazine, the newlyweds took their son, Aleph to an LA Philharmonic concert Tuesday night.

“She was wearing jeans and a T-shirt, her hair was down,” a source told the magazine.  “She looked more concerned about keeping [Aleph] quiet and not disturbing anyone, than anything.”
