Sydney Sweeney is pink perfection in a form-fitting jumpsuit as she glows at skincare event in Los Angeles... following her rare outing with fiancé

Sydney Sweeney radiated elegance and charm as she graced the Laneige Pop Up event in Los Angeles on Monday. 

The gorgeous actress, 26 — who plays a young nun in the new horror film Immaculate — took over the skincare launch in a stunning pink jumpsuit.

Keeping her trademark blonde locks long and loose, the Anyone But You star paired the asymmetrical cut-out number with matching high heels.

Opting for a natural look, she wore minimal makeup, letting her beauty speak for itself, and completed the ensemble with a pair of stylish designer shades.

The outing at the famed Grove outdoor shopping mall comes after Sydney was spotted on a rare outing with her fiancé, Jonathan Davino, in New York City, where she held hands with the businessman during an afternoon stroll.

The couple's cute date followed Sydney's hosting gig on Saturday Night Live, in which she poked fun at affair rumors with her Anyone But You costar Glen Powell, who made a surprise appearance during the sketch show. 

'But the craziest rumor is that I was having an affair with my costar Glenn Powell. That's obviously not true,' Sweeney began in her SNL monologue.

'Me and my fiancé produced the movie together, and he was there the entire shoot,' she explained. 

'And I just want to let everyone know that he's the man of my dreams, and we're still together and stronger than ever. He even came here tonight to support me,' she said, as the camera panned to Powell in the audience. 

The joke comes shortly after Powell opened up about wanting to work with Sydney again on another project while attending the 2024 SAG Awards earlier this month.

'When you find somebody that you really jive with, Sydney is so easy to work with and so fun,' the actor told Variety. 'We're definitely trying to find the next thing. Please send us all the scripts you got. You know we're here for it.'

'It's been really wonderful to read a lot. Sydney reads everything, by the way, and in record time,' the actor said.

'She's the fastest reader I think I've ever met. It takes me a little longer, but we're reading everything and just trying to see what makes sense, what we can turn into something that audiences are going to respond to.'

Sydney and her partner Jonathan have been linked since 2018

The couple got engaged in 2022, with Davino being 13 years older than the 26-year-old HBO star

While few photos of them exist, they were seen at an Emmys party in September 2018 and later photographed at an InStyle and Kate Spade dinner party in October of the same year

'Everyone is always so curious about who I’m with and what’s that like, but I think it’s important to have something for me,' she said

While few photos of them exist, they were seen at an Emmys party in September 2018 and later photographed at an InStyle and Kate Spade dinner party in October of the same year.

In her December 2023 interview with Glamour UK, she discussed her approach to maintaining privacy in her love life.

'Everyone is always so curious about who I’m with and what’s that like, but I think it’s important to have something for me,' she said. 

'I’m very open [otherwise]. I talk about so much and sometimes it gets me in trouble, but I do try to keep something for me.'

With Davino, 'I’ve been in a steady relationship for a really long time, which is not normal in this industry and not normal for my age,' she said. 

Meanwhile, Sydney's horror film Immaculate finished fourth at the weekend box office with $5.3 million in 2,354 theaters. 

The Euphoria star portrays an American nun who decides to join a secluded convent in the Italian countryside, only to uncover unsettling secrets lurking within her new abode.

Glen made a surprise appearance during the sketch show as Sydney jokingly referred to him as her 'fiancé' 

Sydney proudly brought both of her grandmothers, who had roles as extras in her new film, to the premiere in Los Angeles. 

'I flew them to Italy, and they got to come visit me on set. I made them extras as nuns,' she told Today.  'And then I brought them to the premiere in L.A. They were just so excited.' 

Following the breakout success of her romantic comedy Anyone But You, Sydney's portrayal of a nun named Cecilia in the horror film marks a significant departure in her acting career. 

'It's a challenging character; it's an interesting story. I loved the horror genre. It's exciting,' she explained on the morning show.
