Serena Williams, 42, shares stunning bikini flashback photo from a ‘verryyy different time’ in her life… after welcoming second daughter Adira

Serena Williams took to Instagram on Monday night and shared a flattering flashback photo.

The 42-year-old tennis star looked incredibly toned and slim in a little black bikini, which consisted of a low-cut top and tiny thongs with straps over her hips.

The tennis diva sported a diamond piece in her belly button, an I2K trend started by Britney Spears.

Her hair was worn down with curly tendrils falling around her face and her makeup was bright with pale pink lipstick.

“Share a picture from a VERY different time in your life,” the caption captioned the video.

The girl on the cover looked to be in her twenties when the photo was taken. She had a big smile that made it look like she didn’t have a care in the world.

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

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

The caption read: ‘Welcome my beautiful angel.’

The clip shows Serena looking pretty in a pink dress in honor of her new daughter as she walks up to Alexis and kisses him.

Olympia, also in pink, walks over to join her parents, who kiss her, before Serena shows that she forgot something.

The star then returns to the frame holding the couple’s newborn daughter as the family celebrates their second child.

Revealing the baby’s adorable name on Instagram, Alexis wrote: “Welcome, Adira River Ohanian.

“I am grateful to report that our house is coming together with love: a happy and healthy newborn baby girl and a happy and healthy mom.”

‘I feel grateful. @serenavilliams you have now given me another incomparable gift — you are GMOAT. Thank you to all the amazing medical staff who cared for my wife and our daughter. I’ll never forget the moment I met @olimpiaohanian with her sister.

‘Your peace would be like a river, your prosperity like the waves of the sea.’

At the beginning of August, Serena revealed the gender of her daughter together with her husband 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 started dating shortly after.

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

The two later tied the knot during a star-studded wedding ceremony held in New Orleans that November.

Williams announced she was pregnant for the second time just before the Met Gala last May.

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

“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’ve never been so confident or comfortable with babies or children,” she said.

Williams said at the time that she has since learned to embrace parenthood and noted that she has 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.
