Serena Williams introduces her new baby to the world

‘Meet Alexis Olympia Ohanian Jr.’

Serena Williams welcomed her first child with Reddit co-founder Alexis Ohanian earlier this month, with the news breaking just last week.

The couple announced that they were expecting back in April, revealing that Serena was 20 weeks pregnant, and now just five months later, baby Alexis has arrived.

The tennis pro has been laying low since the birth with fans getting their snippets of information from the public congratulatory messages from A-list friend Beyoncé and her sister Venus.

This week however, the new mum has returned to social media, introducing her newborn to her fans and followers.

‘Meet Alexis Olympia Ohanian Jr.’, Serena posted alongside a photo of her cradling her baby girl, telling fans to check out the link in her bio to hear about 'her amazing journey'.

The couple have uploaded a sweet video to her site entitled Hello, World, with the montage of clips taking us through the whole pregnancy from the first sonogram and baby kick to Serena presenting her baby at the end.

'So we’re leaving the hospital, it’s been a long time,' Serena explained at the end of the video. 'We had a lot of complications but look who we got - we got a baby girl.'

The video ends with a profile for Baby Alexis, revealing her birthday: September 1, 2017, her weight: 6lb 14oz and crediting her with the Australian Open win when she was in Serena's tummy earlier this year, with the final line reading, 'Grand slam titles: 1.'
