And the Beckhams did not disappoint on Thursday as they larked around for Halloween, during which they enjoyed quite the A-list experience when David took Harper, eight, trick-or-treating at Justin and Hailey Bieber's home.
Taking to Instagram to share a snap of Harper - who was clutching a snow cone - David revealed they had been to the celebrity residence, which was where she acquired the sweet treat and what she deemed 'the highlight of her life'.

They always pull out all the stops for Halloween so the Beckham brood had gone all out for a night of trick or treating in Los Angeles on Thursday.
