Brad Pitt treated 5-year-old Knox and Vivienne to a day at Legoland Windsor on Saturday, where they sipped fruit drinks and enjoyed the rides.
The British amusement park is getting to be a favorite spot for the family, who visited together in May 2012.
This weekend, though, it was bonding time for Dad and his youngest children, as his partner, Angelina Jolie, is with the rest of the family in Australia, where she is preparing to shoot Unbroken.
Pitt, meanwhile, has been filming Fury in the U.K.
The family did reunite in Hong Kong the previous weekend, where Pitt, 49, and Jolie, 38, celebrated with some shopping at a fancy jewelry store.
