BRAD PITT and ANGELINA JOLIE have stepped out in public with their youngest children for the first time.

Six months after they sold the first pictures of their newborn twins to Hello magazine, VIVIENNE MARCHELINE and KNOX LEON were photographed as their star parents touched down in Japan.

While most families could be forgiven for feeling the heat after a draining 13 hour flight with six young children, Brangelina looked happy and relaxed as they walked through the arrival lounge at Narita International Airport.

Knox matched dad with a trendy flat cap while Vivienne - dressed in a cream cashmere babygrow - appeared alert as she cradled her mother in a body sling.

Older siblings PAX THIEN, MADDOX, SHILOH and ZAHARA - dressed in identical grey cord trousers - were also on their best behaviour as they walked beside their parents.

Fraternal twins Vivienne and Knox were born on July 12 last year in Nice in the south of France.
