Serena Williams has the cutest of sidekicks for her latest fashion campaign - her own little mini-me in daughter Olympia.
The three-year-old teamed up with her famous mum for the 'Footsteps to Follow' campaign for footwear designer Stuart Weitzman.
In the ad, Williams, fresh from the Australian open, and the toddler are dressed in matching white dresses as they dance and strike a pose.
Posting the ad to her Instagram, Williams said' The adventures of Serena and Olympia continue... this time with @stuartweitzman!'.
The ad features captions from Serena about her thoughts on being a mum.
"The best part of being a mum, for me, is having responsibility. Someone that really relies on me," the 39-year-old shared. "And it is waking up every day to see her so happy to see me. It's a feeling I never thought I would experience."
A second clip from the ad, shared to the account Williams' runs for Olympia, shows the pair in matching black catsuits.
"Do you love Mummy?" Williams asks her daughter clip, who answers "Yeah!", before she continues: "I would definitely call Olympia my mini-me. She is mini-Serena."
In the extended version of the clip, Williams says she wants Olympia to do whatever is best for her.
Although the tot is already showing some promising tennis skills.
It's not the first fashion collab for the pair, who also walked the runway together for Williams' label S at the 2019 New York Fashion Week.
Williams also recently joked that the tot had started to call her Serena instead of mama, which the 23 grand slam winner was having none of. Adding Olympia was beginning to understand that other people knew who her mum was.
"I know she knows I play tennis, and I know she knows my name," Williams told the WTA Tour following the Yarra Valley Classic last month.
"It's really weird. She'll be, like, 'Serena'. How do you know my name is Serena? Or she'll see me on TV and either say 'Mama' or 'Serena.' I'm like, You can't say 'Serena,' you have to call me 'Mama'."
