Tennis star, Naomi Osaka has teamed up with toy maker Mattel for its latest Barbie doll which honours the 23-year-old four-time Grand Slam title holder.

The collectible sold out just hours of its release “due to high demand after it was listed.” The message on the manufacturer’s website the directs customers to “Click below, and we will notify you if she becomes available for purchase.”

The new doll is part of the Barbie Role Model series and holds a tennis racket, sports a Nike tennis dress and a white visor. Osaka tweeted that she wore the outfit at the 2020 Australian Open.

“I hope every child is reminded that they can be and do anything,” Osaka added in her tweet.

Osaka is an outspoken figure on the professional tennis circuit and regularly addresses human rights, racial injustice and mental health during interviews.

This is the second time Osaka has collaborated with Barbie, following her 2019 appearance as one of the brand’s Shero dolls.

Earlier this month, video streaming service Netflix released a trailer for its “Naomi Osaka” documentary series, which focuses on her life and her struggles with being catapulted into the public eye.

“Naomi Osaka,” personally narrated by the tennis player, looks back at her upbringing and how her 2018 US Open win turned her into an “overnight superstar.”

The Japanese world No. 2 revealed she had “suffered long bouts of depression” since winning her first grand slam title in 2018. The Netflix series will air on July 16.

Osaka will make her return to competitive tennis at the Olympic Games in Tokyo after withdrawing from the French Open, citing mental health reasons. She later announced she had also withdrawn from this year’s Wimbledon tournament.
