Emma Stone turned heads in a racy black gown at the BAFTA Film Awards in London on Sunday, but it wasn't the daring outfit that had people talking.
Stone, 37, showed off a noticeably slimmer appearance in the Louis Vuitton dress, sparking online speculation about her weight loss.
The actress, who was up for a Leading Actress gong for her performance in Bugonia, opted for a daring look in a form-fitting garment featuring an elegant train and a crossed halter-neck design.
She kept her accessories to a minimum, completing her ensemble with a simple diamond bracelet and earrings.
While the red-headed beauty was widely complimented over her sleek look, some fans expressed concern over her seemingly smaller figure.
'Good lord what happened to Emma Stone? She's so skinny now. What's up with everyone losing SO much weight?!' one concerned fan shared to X, formerly known as Twitter.
'She's much thinner,' agreed another.
Someone else said: 'She was always thin, now she has lost so much weight.'
But other fans leapt to the actress's defense, arguing she has always been thin.
'Whoever is thin shaming Emma Stone in those recent pics... shame on you,' another wrote, in part.
'That's been her body for years,' agreed another.
In 2014, the actress slammed people who said she was too thin, saying genetics and stress are why she had struggled to gain weight.
'It can be really challenging in today's world for anyone, especially girls and women, to feel good about their bodies,' Stone, who was 25 at the time, told Seventeen magazine.
'No matter how things look from the outside, we can all be super critical of ourselves and of our image in the mirror.'
'I've seen articles or comments that have addressed my weight of "caving to pressure to be thin."
'Keeping weight on is a struggle for me, especially when I'm under stress and especially as I've gotten older.'
In January, the Easy A star sparked plastic surgery rumors after debuting a noticeably taut face at the 2026 Golden Globes that stole the show.
'That's the way my genes have decided to go and things will change as time goes on,' she said of her body. 'So when completely untrue statements are made about me or my health, of course a part of me wants to defend.'
The Daily Mail contacted Stone for comment at the time.
