It's not everyday that you spot a Hollywood a lister on the streets of London, but unsuspecting Saturday shoppers came face-to-face with none other than Brad Pitt and Angelina Jolie, along with their entire brood, as they explored one of London's busiest hotspots, Portobello Road.

While a bodyguard followed the group through the crowded streets, neither Brad nor Angelina seemed overly concerned at being recognized by the onlookers as they led their children through the trendy shopping area.

Wearing a flat cap and tinted sunglasses, Brad laughed as he walked hand-in-hand with his look-a-like daughter Shiloh, who was carrying a notebook. Angelina led Vivienne in front, along with one of the children's young friends. Wearing earphones, teenager Maddox played it cool as he hung back with the group's security team.

The family were like any other, chatting happily as they took in the sights, ambling past Notting Hill's Electric Cinema and with the children showing no signs of any rumoured sibling rivalry.

Jolie, Pitt and their brood have set up home in an eight-bedroom, $21,000-a-month (£14,700) rental in Surrey for at least six months, while Pitt films the sequel to his 2013 American apocalyptic action horror film World War Z. Jolie, The UN High Commissioner for Refugees Special Envoy, will focus on issues related to the Syrian refugee crisis and European Union politics during her time in the UK, with the star travelling to the eastern city of Zahleh in Syria on Tuesday for a press conference.

The children are expected to enrol at the The Lycée Français Charles de Gaulle in London.

The Hollywood A listers marriage is the constant focus of scrutiny, following reports that their relationship is marred by jealousy and that the couple are on the brink of divorce. Jolie is said to have fired one of her children's "gorgeous" nannies after she caught her flirting with her heart-throb husband.

The 40-year-old actress is also described as being insanely jealous of actress Marion Cotillard who plays Pitt's love interest in the movie Five Seconds Of Silence. Jolie's insecurity is said to be driving him to divorce her.

However, as they enjoyed a family day out in London, it appeared that contrary to the rumours, divorce couldn't be further from their minds.
