Pregnant Serena Williams

Serena Williams and Alexis Ohanian her fiance

Pregnant Serena Williams cannot stop giggling as she lounges in swimwear while gazing at fiancé Alexis Ohanian during Mexican babymoon

She delightedly announced her pregnancy with fiancé Alexis Ohanian last week. 

And Serena Williams seems to be settling joyously into life as an expectant mother as she jetted away on a babymoon to Mexico, in which she was seen soaking up the sun while gazing adoringly at the Reddit founder on Friday. 

The 35-year-old tennis ace looked totally chilled out as she luxuriated beneath an umbrella while chatting to her partner and sporting a stylish pastel one-piece. 

Serena took to Snapchat last week to confirm she is 20 weeks pregnant, as she made the announcement via a selfie in which she turned to the side while cradling her bump in a tight yellow swimsuit. 

During her chilled-out break, she looked sensational in yet another one-piece as she wore a pink and purple bikini top with a saucy caged detail along her cleavage.

She paired the look with tiny blue bottoms which helped show off her famous derriere - the result of her many hours on the court and in the gym.  As the couple reclined while surrounded by pals, they appeared laid-back and chilled out with Alexis sipping a beer while Serena indulged in a treat.
