WATCH: Serena, Halep Li, Azarenka star in empowering Nike ad

Williams herself was spotlighted toward the end of the relay of woman athletes:

"A woman ... winning 23 Grand Slams, having a baby and then coming back for more?" she asks rhetorically. "'Crazy.'"

The video saw widespread approval online, including from LeBron James ...

Petra Kvitova ...

And Madison Keys:

Williams' husband, Alexis Ohanian, noted that his wife has now been in ads during this year's Super Bowl, Grammys and Oscars.

Serena Williams starred in and narrated a women's-empowerment-themed Nike commercial that ran during Sunday night's Oscars, titled "Dream Crazier."

The ad addressed several of the unfair criticisms that female athletes face, and featured a couple of other tennis players in addition to Williams.

Namely, Victoria Azarenka ...

("If we show emotion, we're called 'dramatic,'" Williams says in the voiceover.)

Or, as fan and blogger Briana Foust put it, an "EGOAT."

Li Na ...

("When we stand for something, we're 'unhinged.'")

And Simona Halep:

("If we get angry, we're 'hysterical,' 'irrational' or 'just being crazy.'")
