Serena Williams has released the first images of her newborn daughter Alexis.

The 23-time grand slam singles champion gave birth on 1 September, and announced on Wednesday that she and her fiance, Alexis Ohanian, have named their daughter Alexis Olympia Ohanian Jr.

Williams posted a picture on her Instagram page showing her cradling her daughter while the couple also shared a video charting the tennis champion’s pregnancy.

A video from Serena Williams and her fiance, Reddit co-founder Alexis Ohanian, announcing the birth of their daughter.

The video shows Williams training throughout the year, winning the Australian Open while eight weeks pregnant, and finishes by announcing Alexis’s name, date of birth and weight.

In the video, Williams says there were “a lot of complications” but does not elaborate.

Last week her coach, Patrick Mouratoglou, said a longer recovery could potentially affect her hopes of returning to the tour in time to defend her Australian Open title in January.

The former world No 1 trained through her pregnancy and has her sights set on overtaking Margaret Court’s all-time record of 24 slam singles titles.

Speaking to Eurosport, Mouratoglou said: “As soon as we feel she is ready to compete, she will. If that is Australia, that’s great. If it’s a bit later, that’s fine.

“She says she still has things to achieve in tennis. She is both a tennis player and a mother, and she has to deal with both of them. She wants to be able to win slams otherwise she will stop.

“For Serena, anything is possible. I cannot put any kind of limit on her. Any time I’ve thought she won’t make it, she did. Which I don’t do any more.”
