Brad Pitt and Angelina Jolie's rented London mansion was flooded with sewage soon after they moved in.
The Hollywood superstars are renting a nine-bedroom mansion in the English capital but were left horrified after issues with one of the toilets.
A source told the Daily Mirror newspaper: "Brad and Angelina were mortified after flooding it as soon as they moved in. There was a big problem with the toilet.
"It caused a fair bit of damage but they managed to sort it out quickly."
The couple and their six children Maddox, 14, Pax,12, Zahara, 11, Shiloh, nine, and seven-year-old twins Knox and Vivienne, have relocated to London while Brad works on the 'World War Z' sequel.
While Brad, 52, will be busy shooting his movie, his 40-year-old actress-and-director wife will use her stint in London to focus on her humanitarian work.
A source previously said: "She plans to focus on political projects dealing with the ongoing refugee crisis in Europe."
This is not Brad and Angelina's first time living in London; in 2012, they splashed out a reported £17,000 a month renting the Whornes Place estate for 15 months while Angelina shot 'Maleficent' and Brad filmed 'The Counselor'.
As they did in their previous stint in London, the couple are expected to send their children to Le Lycee Francais school.
