Updated: Serena Williams to give birth later this year

The Tennis guru, Serena Williams took to her Snapchat page on Wednesday saying that she is expecting her first child; the post was captioned “20 weeks”.

The affixed photo was captured by US media, shows Williams in a yellow swimsuit with what appears to be a baby bump.

Competing in the Australia Open in late January must have been a challenge for Serena as she was already approximately eight weeks along at the time.

And she was most likely four weeks pregnant when Alexis proposed to her in late December.

He popped the question with a large diamond ring, which she showed off in January. They had been dating for only 15 months before he got down on one knee.

'It feels good,' she said of the engagement in late January.

She's pregnant! Tennis star Serena Williams showed off her bump on Wednesday as she revealed is 20 weeks along with her fiance Alexis Ohanian's baby

It's not just the zingy yellow swimsuit that has Serena Williams in a sunny disposition. The tennis star has revealed that there is a baby bump flourishing under her neon one-piece. Exciting!

Serena showed off her lithe, sporty physique and burgeoning bump in a retro-style yellow swimsuit. The flattering swimwear featured high legs and unusual side button detailing.

Williams is primarily a baseline player and her game is built around taking immediate control of rallies with her powerful and consistent serve, return of serve, and forceful groundstrokes from both her forehand and backhand swings. Williams' forehand is considered to be among the most powerful shots in the women's game as is her double-handed backhand. Williams strikes her backhand groundstroke using an open stance, and uses the same open stance for her forehand. Williams' aggressive play, a "high risk" style, is balanced in part by her serve, which most say is the greatest in women's tennis history.

Williams is known for producing exceptional comebacks, particularly on the Grand Slam level. She has won three Grand Slam singles titles after saving match points, (2003 Australian Open versus Kim Clijsters, 2005 Australian Open versus Maria Sharapova, and 2009 Wimbledon versus Elena Dementieva), more than any other player in history. She also came back from a 3–5 deficit in the third set against Kim Clijsters in the 1999 US Open and went on to win her first Grand Slam singles title. In the 2012 US Open final against Victoria Azarenka, she was down 3–5 in the third set and found herself two points away from losing the match. Williams then proceeded to win the next 4 games and defeated Azarenka. In the semi-finals of the 2015 French Open, Williams was ill and barely able to walk during changeovers, yet beat her opponent, Timea Bacsinszky, 6–0 in the third set.

Another improbable win occurred in the third round of the 2015 Wimbledon Championships, when she recovered from two breaks of service in the third set to defeat Great Britain's No. 1 female player, Heather Watson. Williams has bounced back from a set down to win in 37 Grand Slam matches.

In recent years, Williams has shown an ability to serve aces at critical moments. One of these instances was the 2013 French Open final, where in the last game of the match, she fired three aces, including one which clocked at 123 mph (198 km/h) on match point. She repeated the feat similarly against Angelique Kerber in the finals of the 2016 Wimbledon Championships to tie the Open Era record for Grand Slam singles titles. Williams fired three un-returnable serves in her final service game before winning the match and the title with a casual forehand volley on the next point.
