Serena Williams shares throwback photo with sister Venus after announcing pregnancy

Serena Williams, 35, seemed to be getting sentimental about babies by sharing a throwback photo of her and big sister Venus Williams on Thursday.

The photo shows Serena lying down on the bed with Venus smiling brightly at the camera holding a bottle.

She had earlier revealed in April she’s expecting a baby with fiance, Reddit co-founder Alexis Ohanian.

In the blurry photos, both sisters are wearing diapers and Serena’s little feet are kept warm with little baby socks.

She captioned the photo: ‘#tbt to my bff @venuswilliams – that’s me lying down and Venus with the bottle.’Although you can’t see Serena’s face, she looks content to be lying beside her big sister in the photo.
