Day out: Angelina Jolie kept her brood busy in London today with a trip out to the London Aquarium
With their father Brad Pitt busy working on his new movie World War Z, it is up to Angelina Jolie to keep her children busy while they are in London
And the actress has done a great job so far, taking her brood to the cinema to see the latest Harry Potter movie, and allowing little Vivienne to accompany her to pick out some flowers over the weekend.
So today Angelina decided to continue her brood's trip of the capital with a visit to the London Aquarium.
Yawns: Little three-year-old Knox looked a little tired as the family made their way into the aquarium
Dressed casually in a grey jumper and black skinny jeans, Angelina clutched the hands of her twins Knox and Vivienne, while Zahara and Shiloh making up the end.
And the family certainly looked stylish as they made their way into the aquarium.
While three-year-old Knox appeared to have taken style tips from his dad Brad in a pair of taupe chinos and a black T-shirt, his twin sister Vivienne opted for a colourful ensemble of a printed jumper over a checked dress and leggings.
Leading the way: Shiloh and Zahara opted for trousers as they spent time with their siblings
Adorable: Twins Vivienne and Knox are the spitting image of their big sister Shiloh with their blonde hair and blue eyes
Zahara, six, opted for a black vest top and jeans with black biker boots, while five-year-old Shiloh, who is famous for her tomboy style, donned a pair of tan trousers and a dinosaur-print T-shirt.
The only members of the family missing from the day trip were Angelina's sons, Maddox, nine and Pax, seven.
Aquariums are something of a favourite attraction for Angelina and her family, as she was also spotted taking Shiloh, Zahara and Pax to one during a trip to Paris last December.
Keeping busy: Angelina had taken her family to the cinema last week to keep their entertained
Not very glamorous: The children were treated to a private screening of the latest Harry Potter movie
Last week, Angelina treated ehr brood to a private screening of the new Harry Potter film at a cinema in Richmond.
The film, which is rated PG-13, is said to contain some sequences of intense action violence and frightening images.
Yet care-free parent Angelina still took the whole family to watch the action-packed film.
As the family left the theatre after watching the movie a small crowd gathered and local police came to their assistance at they piled into a waiting mini-van.
