Serena Williams‘ recent slimmed-down appearance amid her postpartum weight-loss journey has sparked fan speculation that she may be using Ozempic.

The 43-year-old tennis superstar has been showcasing her toned and svelte physique in social media posts, stunning fans with her transformation.

On Wednesday, the mom-of-two — who retired from professional tennis in 2022 — shared an image of herself on a private plane wearing a black tank top that highlighted her lean arms.

And in a video from earlier this week the athlete — who recently denied claims she’s bleaching her skin — looked slimmer-than-ever as she showed off her dancing s𝓀𝒾𝓁𝓁s in a black tennis dress and neon green shorts.

‘Ozempic anyone,’ one fan wrote, in reference to Hollywood’s favorite weight-loss drug.

‘As a full-time athlete didn’t lose weight or get lean somehow she’s retired and she looks more in shape than she was when she played. Can somebody say Ozempic,’ another wrote.

‘That Ozempic weight loss medicine ain’t no joke,’ another wrote.

Someone else referenced her caption, which read ‘Instagram Vs Reality…’, and wrote, ‘Reality is Ozempic.’

‘My Queen are you ok? You look very skinny,’ another asked. ‘She losing a lot a weight,’ one more commentator chimed in.

The comments continued, with another fan writing, ‘Ok, cheekbones!!!’ and ‘Slim & trim looking great.’

‘Looking beyond fit lady S.’

Someone else added, ‘U lost weight sis looking good.’

‘She looks great. Slightly thinner but still very toned.’

‘Snatched,’ yet another person wrote.

Serena has been keeping her fans up to date during her post-partum fitness journey.

In May, nine months after giving birth to her second child, the Olympic gold medalist took another shot at fitting into her Valentino denim skirt.

‘Ok everyone, I have been working my [peach emoji] off!’ Williams captioned the clip. ‘Let’s see what happens with my jean skirt. Can I fit it yet? Check it out!’

She squeezed into the skirt in front of her mirror, getting caught on her butt as she attempted to pull it up.
