Natalie Portman and her fiancé Benjamin Millepied were together in LA today for a jog around their neighborhood. Their couple's fitness time came after a cultural weekend with their young son Aleph. Natalie visited the Huntington Library and art collection with her boys Benjamin and Aleph, and were photographed taking a stroll along their picturesque grounds. Natalie was casual for their family outing, and today Natalie was decked out in workout clothes. She also represented her undergraduate alma mater Harvard with a crimson cap. Natalie and Benjamin seem to be enjoying the warm temperatures out on the West Coast, which they're soaking up after a stint in the colder climates of France and Switzerland during October.
