Euphoria star Sydney Sweeney is basking in the success of her first line for Frankie’s Bikinis.

The actress, 25, posted a new video to the brand’s account wearing a black bikini and looking every bit the bombshell in the side tie bottoms and scalloped edge top.

Her long hair was wavy and she wore a large cross necklace and she moved and grooved in the video.

She said, ‘I’m so happy you love the first drop of my collection of Frankie’s bikinis. We have more dreamy pieces coming out, tap to sign up for early access so you can get more information.’

The post was captioned, ‘more from @sydney_sweeney coming 4.4.’

The website for Frankie’s Bikinis describes the collaboration with The White Lotus star as the 𝓈ℯ𝓍iest yet.

‘Love Letters by Sydney Sweeney is inspired by the girl who follows her heart, with pieces that highlight Sydney’s gorgeous femininity and sweet romantic aura,’ the web page reads.

The actress turned designer has collaborated on a number of looks in a variety of colors, including green, pink and white.

‘This collection introduces bombshell bikini tops made to tease, one pieces made to flatter, clothing designed to inspire confidence, and personal details from Sydney herself.’

Earlier this week, the Once Upon a Time in Hollywood actress, who is in Sydney, Australia shooting her new film, took a break from filming to check out a cricket match between the Sydney Swans and the Hawthorne Hawks.

In a video shared by the Sydney Swans, the actress couldn’t wipe the smile off her face as she chatted to the shirtless men and posed for photos with them.

‘When Sydney met the Swans. Thanks to the amazing Sydney Sweeney for visiting us,’ the clip was captioned.

The blonde put on a flirty display as she flashed her abs in a beige crop top and wore a Swans scarf for the locker room visit.

At the end of the video, she could be seen doing a cartwheel and giggling on the field.

Sydney attended the game at the Sydney Cricket Ground with her actor pals Dermot Mulroney and Rachel Griffiths.

They were there to cheer on the Swans as they took on Hawthorn, defeating them by 81 points.

Sydney has been Down Under for several weeks now and has been visiting popular tourist spots in Sydney including Taronga Zoo and Luna Park.

Details on the plot of the R-rated flick are being kept under wraps, but the film will also star Bryan Brown, Michelle Hurd, Hadley Robinson and Darren Barnet.

The actress is best known for starring in The White Lotus and playing Cassie Howard in the HBO hit show Euphoria.
