Australian gold medalist Kyle Chalmers' grandparents have officially joined the ranks of Debbie Phelps and Adam Peaty's #OlympicNan as some of Olympic swimming's most adorable parents and grandparents.

They were watching from Australia as Kyle won the Gold medal in the 100m freestyle yesterday. Here's a video of their reactions.

They are too cute. When do they give out the medals for most supportive family members?
