The couple have six children together, including their three biological children and adopted kids Maddox, Pax, and Zahara.
Law enforcement officials told TMZ that police were called to the Pitt-Jolie home on Friday evening (January 5) after a silent alarm went off.
Police in both cars and a helicopter arrived at the scene, but were informed that the alarm had been a mistake made by the children.
A nanny allegedly apologised for the mistake on behalf of Jolie and Pitt, who were not present during the incident.
Pitt and Jolie are rumoured to have had a private wedding ceremony on Christmas Day. Neither star has commented on the report.
