Margot Robbie made waves at the Chanel show during Paris Fashion Week with her stylish bob haircut, but it was her noticeably slim figure that caught the attention of many attendees.

The 35-year-old actress graced the event in a laid-back ensemble, featuring loose-fitting denim jeans and a sheer white vest that showcased a lace bralette underneath. She completed the look with Chanel ballet flats.

As a Chanel brand ambassador since 2018, Robbie accessorized her outfit with a leather handbag and a scarf, which she elegantly draped over her shoulders later on.

While her fresh hairstyle and casual attire were a hit, some observers couldn’t help but focus on her slender appearance, sparking speculation about whether she might be using a weight-loss drug.

“We’ve lost another one,” lamented one commenter, alluding to other celebrities who have faced similar speculation.

“I mean, she looks Ozempic-d,” another remarked, referencing a popular weight-loss medication.

‘I hope she hasn’t taken that weight loss stuff too, because she was already gorgeous,’ another alarmed fan wrote.

‘But what the f**k is going on in Hollywood?’ questioned another.

Many couldn’t help but notice the mom-of-one’s slender look

‘I can’t believe Margot Robbie fell into the Ozempic trap,’ another dismayed user wrote.

Someone else declared that they didn’t ‘recognize her at first’. 

Others defended the star, arguing she has always had a slender frame: ‘She’s fine. Margot’s always been thin.’

Someone else hypothesized it was ‘the blush and hair placement’ that made her face more narrow. 

‘Seriously, you’re all going crazy with this Ozempic hunt,’ slammed another. ‘Margot Robbie has always been slim and with that exact build.’

The Barbie star and husband Tom Ackerley welcomed their baby boy in October 2024.

The Oscar nominee previously opened up about her approach to diet and fitness, revealing she indulges her sweet tooth most of the time but will eat clean in the lead-up to a movie. 

She told Emirates Woman: ‘I’m not good at doing moderation. I get miserable if I don’t eat. I can’t just have a salad every day and a half a glass of wine every second day. I can’t do it.’ 

The actress, 35, opted for a very relaxed outfit, wearing loose denim jeans and a sheer white vest, that showcased her shrinking physique

Detailing her stricter ‘clean’ diet, she said that for breakfast she’ll typically eat oatmeal with blackberries or a ‘green machine’ smoothie with kale and apple.

At lunchtime, she’ll have something like lemon chicken with brown rice or mackerel salad with tomatoes and cucumber.

Dinner is typically tuna steaks with sweet potato or a vegetable hot pot with rice noodles.

Robbie added that while she enjoys a glass of wine every so often, she bans saturated fats, fast food, sugary drinks and chocolate in the lead-up to an event or a premiere.

While she loves intense cardio workouts and running, the star explained how she trained her strength and improved muscle mass when she was working on the 2017 film, I, Tonya. 

The actress’s appearance at the Chanel show comes after her Wuthering Heights promo tour with fellow Australian co-star Jacob Elordi.

The Emerald Fennell-directed romance surged past $150 million worldwide, cementing itself as one of the year’s biggest theatrical surprises just two weekends into its run.

The Warner Bros./MRC release added $14.2 million domestically, while Sony Pictures Animation’s GOAT edged out the top North American spot with $17 million, according to Deadline.
