Shiloh Jolie-Pitt was reportedly devastated to receive an "educational" game from the Tooth Fairy instead of money.
The six-year-old daughter of Brad Pitt and Angelina Jolie was excited when one of her teeth fell out after her brothers Maddox, 10, and nine-year-old Pax, told her to expect cash from the Tooth Fairy for leaving her incisor under her pillow - but the celebrity couple gave her a copy of the kids' version of Trivial Pursuit instead.
A family friend told the National Enquirer magazine: "Shiloh can be quite the traditionalist when it comes to some things, including the Tooth Fairy.
"Her brothers Maddox and Pax got her all worked up after she lost a tooth and left it under her pillow. They told her to expect a big wad of cash.
"When Shiloh woke up, the tooth was gone but there was no money and she was fuming. She felt she had been ripped off."
Shiloh - who also has siblings Zahara, seven, and three-year-old twins, Vivienne and Knox - then asked if she could get the tooth back to sell it for a better deal, but Angelina refused and put the experience down to being an important life lesson for the youngster.
She added: "Shiloh asked her folks if she could get her tooth back from the fairy so she could shop it around and get a better deal.
"In the end, Angie sat Shiloh down and explained that Tooth Fairy gifts are non-negotiable and that sometimes life can be disappointing, but there's always a next time."
