A spokesperson for Serena Williams has confirmed the tennis star is pregnant.
The world number two is due to give birth in the autumn.
The 35-year-old posted a picture on Snapchat with the caption 20 weeks - but then deleted it yesterday.
It means the tennis star was pregnant when she won the Australian Open in January.
