Most of you would know Rihanna as the baddest popstar on the planet but she's also doing some incredible work as a humanitarian.
She won Harvard's Humanitarian Of The Year award and she's been working as an ambassador for Global Partnership for Education (GPE), a charity that aims to provide every child with basic education.
Her charity Clara Lionel Foundation has teamed with GPE and aims to raise $3.1 billion over the next few years to bring education to 870 million children around the globe.
Recently, she visited Malawi in South-East Africa with her new BFF and our former Prime Minister Julia Gillard to talk through the issues and also visit the classroom.
RiRi is a natural maths teacher, as a short doco on the trip shows and she also knows exactly how the kids learn.
"It's amazing, the way they learn though," she says.
"I love that they learn in melody, that's like my favourite thing. Kids adopt melody really, really quickly. If you can adopt that as a learning tool, it's the most brilliant thing."
