Meet Mavis Williams. She is Olympic gold medallist Adam Peaty's biggest fan.
And she is also his grandmother.
Self-branded as "Olympic Nan", Williams is now the internet's favourite grandma, thanks to her unwavering support for her 21-year-old swimmer grandson.
Peaty stormed to victory in the 100m breaststroke in 57.13 seconds, smashing his own world record for the second time in two days to scoop Britain's first men's swimming gold in decades.
Naturally, his nan took to Twitter to celebrate her famous grandson's biggest achievement.
A camera crew from the BBC was on hand to capture her erupting with joy as she watched her grandson make Olympic history.
She later told ITV's Good Morning Britain she is "proud as punch" of her grandson.
She said: "I went ballistic, (I was) excited and very pleased for him because he's worked so hard for it and I knew he would do it but I wouldn't let on. It was exciting from the word go, I just had my hands in front of my eyes until he was off the block."
It's obvious Olympic Nan is her grandson's biggest fan and cheerleader.
In fact, here she is getting her nails done to show support ahead of Rio.
The proud nan even covered her house in bunting.
She's always the first to tweet about her grandson's achievements.
Her support is unwavering.
Not to mention her emoji game is pretty strong.
At the moment her Twitter bio reads: "Proud Nan to a World Champion Breaststroker."
We think she should add "and Olympic gold medallist" to that. Don't you?
