Since hanging up her racket, Williams has had more time to hang out with her 1.6million TikTok followers.

Over the weekend, she left fans stunned by lifting the lid on one of her more unusual remedies.

In a previous video she told of how she’d been urged to rub breast milk on her kids’ wounds as it would help them heal.

Williams, 42, claimed that she would “try it for like a week” before providing a further update.

The 23-time major singles champion later revealed: “It works for my kid”.

As she was suffering from sunburn under her eye she dabbed some on her own face.

A few days later, Williams went on to admit: “Ok is this totally weird???

“I have to say after a week of using MY breast milk under my eye – it worked!”

One harsh fan wrote: “Disgusting.”

While a second commented with a gif saying: “That is weird.”

A third left a shocked-looking emoji.

But others were supportive of Williams.

One commented: “Good for her!”

And a second claimed: “Breast milk is the best medicine for skin.”

Another added: Breast milk is magic.”

Williams has been enjoying herself in retirement.

She recently attended a US Women’s National Team soccer game, while she has also been to watch Inter Miami.
