British swimmer Adam Peaty won his first Olympic gold medal yesterday. As if a gold medal wasn't enough, Peaty also smashed his own world record in the 100m breaststroke during a qualifying heat. Surely, everyone in the UK is proud of Adam, but no one is prouder than his grandmother, Mavis.

Mavis has become quite the internet celebrity in recent weeks, taking to Twitter to voice her support for her grandson in the most adorable grandma way possible.
