Serena Williams has been teaching her daughter Olympia the ropes of tennis.

The tennis champ and her mini-me toddler took to the courts on Friday for a quick game in the sunshine, with the mum-of-one sharing rare snaps of her daughter.

She's putting in the work ahead of the US Open, which is still scheduled to take place in New York later next month.

The tennis pro, 38, was seen high-fiving her two-year-old as they geared up for a sweaty session, coached by Serena herself.

They looked incredible as they were twinning in matching purple Nike leotards for the game, while clutching Wilson racquets.

Serena looked stunning as she showed off her athlete figure while in focus.

Meanwhile, little Olympia was mimicking her mum's actions as they posed for photos together.

Serena can be seen holding her racquet and squatting her knees, while Olympia is copying her actions.

Serena and Olympia later pose together in front of the net, and they show off their striking resemblance.

She also shared a heartwarming video clip of herself and Olympia doing a celebratory high-five on the court after they had finished their game.

She is still determined to win her record 24th Grand Slam title.

The star won her 23rd Grand Slam championship in 2017, and was eight weeks pregnant with her lookalike daughter.

Just a month before the game she went public with her engagement to her Reddit co-founder husband.

They later tied the knot in November 2017 - two months after Olympia's birth.
