They looked every inch the trendsetting trio as they headed to the farmer's market in Los Feliz yesterday.
While Natalie Portman and fiancé Benjamin Millepied both donned sunglasses and hats in an attempt to go incognito, little Aleph stood out in an electric blue onesie and navy socks.
Meanwhile, Oscar-winning actress Natalie looked cute in a rust-coloured summer dress and sandals as she and her beau doted on their adorable baby while checking out the local produce.
The pair took it in turns to tote their precious luggage, with French dancer Benjamin looking confident as he held on to his six-month-old son.
Natalie was later seen carrying Aleph in a sling around her neck as the pair picked up some groceries at the market.
Despite being just six months old, Aleph is already something of a well-travelled tot, having spent a few days earlier this month in his mother's home country of Israel.
Natalie, who was born in Jerusalem, was accompanied by Benjamin and Aleph on her trip home, where she introduced her son to her relatives in the country.
Since giving birth to baby Aleph, Natalie has been pondering what to do when she returns to the acting industry.
And it was recently claimed that the 30-year-old actress is considering the sci-fi movie Jupiter Ascending as her first post-baby movie return.
Natalie is said to be in talks with writers Andy and Lana Wachowski to star in the film, which is set to start production in the autumn for a 2014 release.
It has also been reported that Natalie is planning to shoot a documentary about veganism, hoping to turn Jonathan Safran Foer's novel Eating Animals into a film.
In a recent interview with a French website, Foer said: 'She contacted me, she told me that she loved the book. I know her now.
'I will help her eventually but it will be her vision. She’s only at the very beginning.'
