Serena Williams and husband Alexis Ohanian have been somewhat guarded when it comes to sharing images of the newest member of the family, Adira, with the public.

But on Thursday the retired tennis legend, 42, took to TikTok and gave her 1.6 million fans and followers a glimpse at a personal but heartwarming moment inside her home.

In the short clip, Olympia can be seen being absolutely adorable with her 𝚋𝚊𝚋𝚢 sister, pinching her cheeks while doing 𝚋𝚊𝚋𝚢 talk.

Off the top of the clip, big sis immediately grabs at Adira’s left cheek, as Williams gives her new born a kiss on her head and then tries to open a box of cereal while cradling her in her arms

While squealing, Olympia begins to rub her left cheek ever so lightly, and then grabs ahold of her left arm and slightly moves it along to a song she stars to hum out loud.

With high-rise buildings in the backdrop of the video, the patient mom remained calm, cool, and collected during her multi-tasking exhibition.

The clip appears to have been shot in the morning hours, considering the 23-time Gran Slam singles tennis champion is dressed in pink and white-patterned pajama bottoms with a matching spaghetti-strap top.

She has her lightened locks flowing down long past her shoulders with plenty of natural curls and a part in the middle.

Olympia looks to be dressed in light blue pajamas and her hair styled in cornrows that are pulled into two ponytails.

It turns out the cheek-grabbing has become more of a trend for Olympia when it comes to showering her sister with attention.

‘Olympia is obsessed with being a big sis,’ the legendary tennis champion began in the caption of the clip, before adding,’ She’s always pinching Adira’s cheeks.’

She also added the hashtags: ‘#𝚋𝚊𝚋𝚢tok #bigsis #siblingsbelike #olympiaohanian #adiraohanian #siblingcheck #siblinggoals #daughters #momtok #momsotiktok #fyp #foryou’
