Serena Williams flaunts her curly hair while enjoying a playdate in sandbox with her daughter

Tennis champion, Serena Williams recently reached ten million followers on Instagram, and who better to celebrate it with than her trusty sidekick, Miss Olympia Ohanian.

Williams, 37, shared the photo of a joint playdate with her one-year-old daughter, Olympia. Mother and daughter coordinated in black outfits, with Olympia rocking a dramatic onesie that said “More issues than vogue.”

The venue of the playdate was a covered sandbox, probably Olympia’s, and the pair was surrounded by buckets and shovels.

Alongside two heart emojis, Williams wrote:

“For my 10 million followers. Thank you.”

Her followers immediately took to the comments section to let her know just how welcome she is:

“You're so amazing, Serena. No matter what, you'll always be one of my heroes. Keep fighting and following your brightest path.”- @brydee_styles

“You are more than welcome, enjoy your day with your precious little one- @iberianurse02

“You're welcome, but thank you for sharing your amazing life with us!!”- @free2live2

SANDBOX DAYS

Meanwhile, the sandbox appears to be a favorite spot for the tennis star and her daughter. Last month, Williams was spotted getting some “workouts” done with Olympia. The cute tot, however, was more interested in playing with her yellow toy truck.

Despite her busy schedule as an athlete, a mom, and a business owner, Williams always makes time for her only child with husband, Alexis Ohanian. She told People Magazine in September:

“I have spent every day with Olympia since she was born, and one of the latest challenges has been her teething. I’m sure a lot of parents can relate.”

5-STAR HUBBY

It helps to have a supportive husband like hers, and Alexis is not just a hands-on dad; he also has Williams’ back in everything else. Recently, the Tech mogul was on Twitter to slam the double standards applied to judge his wife's controversial outburst at her U.S. Open loss last month.

Many criticized the 23-time Grand Slam winner for her emotional reaction during the game, and an Australian paper even went as far as publishing a derogatory illustration of the event where they portrayed Williams as a black baby throwing a tantrum.

Then, some weeks ago, Brett Kavanaugh, who has since been voted in as Supreme Court Justice, became emotional during his testimony in front of the Senate as he denied sexual assault allegations leveled against him.

The Democratic candidate for Alabama, Deborah Barros, took to Twitter over the weekend to compare both events, saying:

"Funny how a black female tennis player is held to a higher standard to keep her emotions in check than a Supreme Court nominee."

Alexis responded to the tweet with a couple of his own.

“It's not funny, it's [expletive],” he corrected.

“If you’re going to be a Supreme Court Justice -- a job that requires maintaining sober judgment -- it shouldn't matter what questions you have to answer in your job interview, you keep it together.”

“I look forward to the cartoon @damonheraldsun puts on the front page about it.”
