Serena Williams unveils first photo of baby daughter Alexis

The tennis superstar gave birth to her first daughter on September 1, but until now we haven’t known any details of the tot.

However, Serena and boyfriend Alexis Ohanian have now debuted their offspring on Instagram – and she’s been named after her daddy.

In a sweet picture, Serena, 35, held the cutie – who has quite the head of hair – with the caption reading: ‘Meet Alexis Olympia Ohanian Jr. You have to check out link in bio for her amazing journey. Also check out my IG stories.’

And her Instagram story, plus a video shared to Serena’s offical website, showed Alexis’s journey into the world.

Beginning at Serena’s baby scan, we saw selfies of the athlete with a growing bump, behind the scenes Snapchats of her tummy moving, all culminating in the baby’s birth.

Serena hinted at a difficult birth, saying: ‘We had a lot of complications, but look who we got!’

She added that she had spent six days in hospital.
