US tennis star Serena Williams has revealed that she will be spending the next six weeks in isolation due to coronavirus fears.

The 38 year-old, who has 23 Grand Slam titles to her name, announced the news on social media.

She wrote: "Spending the next 6 weeks in solitude. Being a wife. Being a mom. Cooking. Cleaning. Spring cleaning. Face mask. Makeup tutorials. I’ll let you know how it goes.... stay safe everyone. This is serious."

Williams' 2020 on-court season has been up and down as she got knocked out of the Australian Open third round against Wang Qiang in January. But a few weeks earlier she took home the ASB Classic title in the singles and doubles.
