A hilarious video has emerged of a young woman's devastated overreaction to the news that, arriving back from a night out, her mother had eaten her pizza.

The footage, shot by her brother near Belton, UK, on Monday shows 18-year-old Olivia Shaw's intense tears after missing out on the food.

Olivia called the incident the "WORST. DAY. EVER!!" but eventually ordered a new pizza, recovering from her tired and emotional reaction and later laughing about it online.
