It looks like Serena Williams' daughter has inherited her mum's tennis talent.
The 23-grand-slam-winner shared a sweet pic of herself schooling Alexis Olympia (who goes by Olympia) on the ins and outs of the game.
In the pic, Olympia, three, can be seen concentrating as she holds the racket at an angle, feet pointed just so, ready to return serve on the family's home tennis court, while her proud mum watches on.
It looks like Williams, 39, has been giving the tot a rundown of the important tennis techniques, captioning the pic 'turn, back, reach, head, follow through'.
The toddler also shares her famous mum's love of fashion, sporting a hip black and white Nike tennis outfit - the same outfit her doll wore to the tot's very first tennis lesson in October.
The little girl has proven a keen student, even studying her mum's moves on court.
It's not just Williams' fans who were impressed by her aptitude, with tennis legend Billie Jean King praising her skill.
"Look out, world! Keep going for it!," the former world number one commented.
Olympia appears to have learnt a lot since her very first lesson last year, after Williams signed her up without telling the instructor who her new student's famous mum was.

"Guys, I signed Olympia up for tennis lessons," she said in an Instagram story documenting the big moment.
"Don't even start with me, because I'm not giving her tennis lessons; I signed her up for some. But the lady has no idea that it's my daughter, so we'll see how long that lasts."
Williams, who shares Olympia with husband and Reddit co-founder Alexis Ohanian, has been sharing updates as the family keep things low key during the pandemic.
Including a video showing Olympia giving her a 'Covid' test by pushing an improvised 'swab' up Williams' nostril and sweet snaps of the pair cooking together.
