British Olympic swimmer Adam Peaty has plenty of fans supporting him from the stands. But his biggest fan of all - his grandmother - is cheering him on via Twitter. 

Peaty's 74-year-old grandmother Mavis Williams has dubbed herself #OlympicNan, and has been tweeting emoji-laden messages of encouragement to her grandson as he competes in the Rio games from her home in Staffordshire, England.

It seems that her cheerleading has helped: Peaty, 21, broke his own world record in the men's 100m breaststroke on Sunday, snagging the gold medal in the process. It was Great Britain's first medal of the games and the country's first swimming medal since 1988.

#OlympicNan couldn't have been prouder. Here's a look at some of the tweets she's posted thus far:

People on Twitter are loving her level of support:

And in case you can't get enough of this proud grandma, the BBC caught up with #OlympicNan and shared a video of her watching her grandson compete.
