The adorable children were out with their model mum and daddy, Alessandra's fiancé Jamie Majur, on the Fourth of July in Malibu.
Both mum and daughter marked the day with their clothes – 31-year-old Allessandra wearing a Dolce & Gabbana star jumper, and her three year old with a t-shirt bearing the American flag in the shape of a heart.
Even two-month-old Noah managed to get red white and blue in his outfit.
The little boy, who was also held by his Californian businessman dad arrived on May 7.
His Brazilian mum has clearly had no problems regaining her enviable figure, as she did following Anja's birth in 2008 – walking the catwalk for Victoria's Secret three months after giving birth.
She's expected to appear with her fellow angels at the opening of the lingerie brand's London store on July 25.
