Serena Williams left the tennis world in a state of confusion last night after posting a selfie subtitled "20 weeks", only to remove her Snapchat announcement soon after.
The 35-year-old collected her 23rd Grand Slam win of an fantastic tennis career at this year's Australian Open that saw her surpass the Open era record set by Steffi Graf.
After securing the biggest win over her career against Caroline Wozniacki in the Miami Open final, Konta said: "I play smart tennis and calmer tennis, I think".
The beginning of Williams' maternity leave coincides with the imminent return of two other big names on the tennis stage.
But while the American will realistically miss the next four Grand Slams, she is planning on returning to the WTA Tour in 2018, her spokeswoman Kelly Bush Novak confirmed.
The 35-year-old tenniswoman posted a picture of her with the rounded stomach and specified that she was at "20 weeks" of pregnancy.
Serena's snap suggests that she won the Australian Open without dropping a set while pregnant.
Court, the woman she's chasing in terms of Grand Slam titles, also won her final three titles in 1973 after giving birth to her son Danny a year earlier.
The great Australian player herself took time away from the pro tour when she married, and again after she had her first child, on both occasions coming back to win multiple Major titles.
Maria Sharapova, who incidentally turned 30 on the day that the Williams' news broke, has serving a doping suspension since the Australian Open previous year, but is due to return next week.
Williams announced her engagement to Alexis Ohanian, co-founder of social media outlet Reddit, last December. "It's not good for women's tennis which is a shame", she said.
Former world number one Caroline Wozniacki, a close friend of Williams, also welcomed the news.
For Williams, who commands almost $29 million in salary and sponsorship earnings, becoming pregnant makes her all the more attractive to corporate sponsors, industry executives said.
Williams is the oldest woman to win a Grand Slam singles title and still dominates the tour at an age when most players have retired.
Williams, who has played professionally for two decades, first gained the No. 1 ranking in 2002 and has held that spot for more than six years in total.
