Serena Williams, 42, looks stunning in a white swimsuit 9 months after welcoming daughter Adira: ‘Hot girl summer body – here I come!’

Serena Williams shared sexy swimsuit snaps taken in a pool on Instagram on Friday.

The 42-year-old tennis star looked incredibly toned and slim in the white swimsuit.

The tennis diva looked slim after welcoming her second child last year.

Her long blonde hair was curled and worn over her shoulders, and her makeup was light with light pink lipstick.

‘Water aerobics is a great way to add some fun to your workouts. Get ready for that hot summer girl body – here I come! @wyn, Beauty You Can Move In,” the athlete wrote in her caption.

In February she expressed her self-confidence.

“I notice that I have to remind myself of that self-love at all stages of my life,” said the tennis star.

She then talked about her figure, which looked in great shape.

“Right now, I love that my body isn’t perfect,” she said.

“I love that I smell like milk – that milk supports @adiraohanian. I like to get to know a new version of my body.

“It’s a change, but it’s a change that has been well worth it. So start this week knowing that you are loved, and it starts with you.

“Okay, now I’m going to the gym. Serena.’

This comes after the athlete welcomed her second daughter with husband Alexis Ohanian in August.

She shared a sweet video of herself, husband and daughter Olympia, five, with newborn baby named Adira River Ohanian.

The caption read: ‘Welcome my beautiful angel.’

In the video, Serena looks beautiful in a pink dress in honor of her new daughter as she walks up to Alexis and kisses him.

Olympia, also in pink, walks towards her parents, who kiss her, before Serena indicates that she has forgotten something.

The star then walks back into view cradling the couple’s newborn daughter as the family celebrates their second child.

Alexis revealed the baby’s adorable name on Instagram, writing, “Welcome, Adira River Ohanian.

‘I am grateful that our home works together with love: a happy and healthy newborn girl and a happy and healthy mom.

In October, she shared a sexy flashback photo in a swimsuit.

“Share a photo from a VERY different moment in your life,” was written across the snapshot.

The cover girl appeared to be in her twenties when the photo was taken. She flashed a big smile that made it seem like she wasn’t worried about anything.

‘I feel grateful. @serenawilliams you have now given me another incomparable gift: you are the GMOAT. Thank you to all the wonderful medical staff who cared for my wife and our daughter. I’ll never forget the moment I introduced @olympiaohanian to her sister.

“Your peace would have been like a river, your well-being like the waves of the sea.”

At the beginning of August, Serena and her husband revealed the gender of her daughter at a party.

The tennis player and her husband first met when they bumped into each other at a hotel in Rome in May 2015, and they started dating not long after.

The couple got engaged in December 2016 and welcomed daughter Olympia in September.

The two then tied the knot in a star-studded wedding ceremony that took place in New Orleans in November.

Williams announced just before the Met Gala last May that she had become pregnant for the second time.

The former athlete spoke about motherhood during an interview with Fashionwhere she expressed that she did not see herself as a parent in her younger years.

‘Earlier in my career I never thought about having children. There were times when I wondered if I should ever bring children into this world, with all its problems. “I never felt confident or comfortable around babies or children,” she said.

Williams went on to say that she had since learned to embrace parenthood, noting that she had become especially attached to her daughter.

“The fact is that nothing is a sacrifice for me when it comes to Olympia. It all just makes sense,” she said.
