(CNN) It must run in the family.
Serena Williams shared an adorable video of her 3-year-old daughter Olympia joining her on the court while practicing ahead of the Australian Open.
The tennis star, who is currently isolating in Adelaide but is allowed out for practice sessions, posted the footage on Instagram alongside a caption that wrote: "Footage from my practice before leaving with my training partner."
Olympia is seen attempting a ferocious backhand before sitting down and throwing balls to her mom.
It's not the first time the pair have been seen side-by-side on the court.
The 23-time grand slam champion posted a similar video back in July, with the pair wearing matching purple outfits.
