Talk about snap back! Serena Williams shared a mirror selfie on Instagram, wearing a black and white T-shirt and tiny shorts, showing her incredible post-baby body less than a month after the birth of her daughter, Alexis Olympia Ohanian Jr. The 23-time Grand Slam champion showed her toned thighs and flat tummy confidently, looking ready to return to competitive tennis in no time. The 36-year old  previously revealed she was back in her jean shorts just two weeks after giving birth with a selfie posted on her Snapchat.

Serena and fiance Alexis Ohanian welcomed their first child together on the 1st of September and introduced her to the world on the 13th of September.

Less than a month old, Alexis Olympia Ohanian Jr already has her own Instagram account with thousands of followers.

Serena Williams has also been sharing her joys of motherhood on Twitter. “I’m having a hard time posting about anything that does not involve Alexis Olympia or something to do with her,” she lovingly posted. The new mom also posted a fun fact about winning the Australian Open while she was pregnant.

Serena Williams is expected to return to tennis in January, at the start of the 2018 season.
