Simone Biles served up plenty of #BlackGirlMagic in becoming the first American woman to win four gold medals in one Olympic Games.

In doing so, the gymnastics sensation has moved into the company of Olympic greatness, already sharing a Sports Illustrated cover with swimmers Michael Phelps and Katie Ledecky.

Well, whether it was the SI photo shoot or at some point during the Olympic Games in Rio de Janeiro, Phelps passed down some wisdom to the 19-year-old Biles, which she tweeted about Sunday morning.

And the most celebrated Olympian of all time, with 23 gold medals to his name, may add the title of gold medal-stacking teacher to his resume.

Simone is a quick learner, too.

Her four gold medals and one bronze were stacked to perfection in this photo.

It's great that Phelps taught Biles how to stack gold medals like a boss.

With the 2020 Olympics in Tokyo next, Simone will probably have to make room for more.
