Macron met Friday in the capital, Dakar, with President Macky Sall and is inaugurating a school before attending a meeting of the Global Partnership for Education.
Speaking at the event, Rihanna said while tremendous progress has been made, there's still a long way to go, and the fight isn't over until every boy and every girl in the world has access to education.
Rihanna has been less vocal in her activism than some celebrities, but she has always been supportive of the LGBT community.
The French leader told delegates that countries where the world had witnessed "democracy being rolled back", were also where "girls were being pushed out of school".
However, the masses may not know her most important work as a humanitarian and ambassador for Global Partnerships for Education (GPE). France is donating 200 million euros to the partnership.
Donor nations announced on Saturday (Feb 3) US$2.3 billion in funding to support education in developing countries, following an global meeting in the Senegalese capital Dakar.
The conference is held to raise funds for education in impoverished nations.
A rapid reaction force of Senegalese troops was recently deployed to Mali as part of a UN peacekeeping mission with France's blessing, as the global community attempts to contain Al-Qaeda-linked groups wreaking havoc in the unstable desert nation. The conference, in turn, asks the partner countries to spend 20% of their public spending on education - a level that can be particularly hard for countries struggling with jihadists or civilian conflicts.
"I would like to thank President Macron for having me".
