Olivia Wilde turned heads at the San Francisco International Film Festival this week, appearing noticeably slimmer in a look that has reignited speculation about possible use of the diabetes drug Ozempic for weight loss.
Red Carpet Appearance
The 42-year-old actress and filmmaker wore a long, oversized skirt that concealed the lower half of her body, paired with a small white T-shirt that accentuated her lean, muscular arms. Her appearance quickly became a topic of discussion on social media.
Some fans questioned whether she had used semaglutide, the active ingredient in Ozempic, while others argued that harsh red-carpet lighting distorted her features. One fan wrote: 'That's age, not Ozempic. She has always been skinny.' Another added: 'She has ALWAYS been on the thinner side and this is taken by a wide angle which further distorts her features.'
A third commenter said: 'Why would she be using Ozempic when she's been thin all her life?' while another noted: 'It's not Ozempic, she's always been very thin. This is just a [bad] makeup job.'
Daily Mail has contacted Wilde's representative for comment.
Previous Speculation
Earlier this month, social media users accused Wilde of using Ozempic after she showed off her slender physique in a tiny crop top at the Fashion Trust US Awards in Los Angeles. The actress has long been known for her commitment to fitness, often spotted hitting the gym in Los Angeles. She avoids processed foods and enjoys classes at the Tracy Anderson Method Studio in Studio City.
While training for her role in 2010's Tron: Legacy, Wilde did cardio five days a week, strength training three days a week, and mixed martial arts classes as regularly as possible.
Personal Life Updates
The appearance comes amid news that Wilde's ex-boyfriend Harry Styles, 32, is engaged to actress Zoe Kravitz, 37. Wilde and Styles dated for nearly two years before breaking up in November 2022.
On Monday, Wilde was seen reuniting with ex-fiancé Jason Sudeikis as they dropped off their children. The former couple, who were together from 2011 to 2020, share son Otis, 12, and daughter Daisy, nine. Despite a tumultuous past, they shared a hug, demonstrating amicable co-parenting.
Their relationship ended dramatically when Wilde began dating Styles while shooting her film Don't Worry Darling in late 2020. She split from Sudeikis in November 2020 and went public with Styles in January 2021. Wilde has denied infidelity, telling Vanity Fair in October 2022: 'The complete horses**t idea that I left Jason for Harry is completely inaccurate.'
In January 2025, an insider told DailyMail.com that Wilde was emotionally 'moving forward' from her relationship with Styles, more than two years after their breakup. 'After the Harry breakup, she really took time off dating and away from the spotlight to focus on herself and her family,' the source said. 'She got way too caught up in that and their relationship became a public spectacle.'
Wilde is now dating art dealer Caspar Jopling, to whom she was first linked in September 2025.
Upcoming Projects
Professionally, Wilde is busy with several exciting projects after a four-year hiatus from films. In July, she will star alongside Charli XCX in director Gregg Araki's erotic thriller I Want Your Sex. She will then join Pedro Pascal and Will Arnett in the drama film Behemoth, directed by Tony Gilroy.
