She shares her little daughter with her husband Alexis Ohanian, the co-founder of Reddit, whom she married in 2017 in New Orleans.

At one point she sat down beside the court and tossed tennis balls to Serena so that the pro athlete could get along with practice on her own.

‘Footage from my practice before leaving with my training partner @olympiaohanian,’ wrote Serena when she posted the Tik Tok to her Instagram.

Here and there: Olympia took on several roles during the practice session – sometimes she was on the same side of the net as her mother and sometimes on the opposite end

She and her sister Venus Williams, who is also a famous tennis player, arrived in Adelaide this Monday to train for the Australian Open which begins February 8.

In October of last year Serena revealed on Insta Stories that little Olympia has been signed up for tennis lessons herself.

However she was to be instructed by neither her mother nor by her aunt Venus, according to Serena’s posts at the time.

In fact Serena shared that the teacher they have chosen at that point had ‘no idea’ that her new pupil is the daughter of a world-famous athlete.

She also said she would leave the lessons immediately after dropping Olympia off so as not to be an ‘overprotective’ or ‘distracting’ influence.

However last week she posted a sweet Instagram snap of herself looking on lovingly as Olympia practiced her tennis moves.

Meanwhile earlier this month Alexis leaped onto Twitter to slam Romanian billionaire Ion Tiriac for being critical of Serena.

Ion, who used to be a tennis player and is now president of the Romanian Tennis Federation, made the remarks on TV in his native country.

‘At this age and the weight she is now, she does not move as easily as she did 15 years ago,’ said Ion, adding that she ‘was a sensational player. If she had a little decency, she would retire.’

In response Alexis tweeted a screen-grab of a Google result showing Ion had no Grand Slam singles titles and taunted him: ‘Had to Google it… turns out my 3 year old has more Grand Slam victories than this.’

Alexis, whose wife has 23 Grand Slam singles titles, wrote: ‘2021 and no holding back when a racist/𝓈ℯ𝓍ist clown with a platform comes for my family.’

Ion did win one grand slam in men’s doubles at the 1970 French Open and as of 2019 was the third-richest businessman in Romania, Forbes reported.

He himself retired from tennis in 1979, the year he turned 40, which is the same age Serena will turn in September of this year.

Last September Serena had to withdraw from the French Open as she was still recovering from an injury to her left Achilles tendon.

However next month she is slated to play in the Australian Open in which she has won a record seven victories, most recently in 2017.
