Sydney Sweeney slips into skimpy lingerie to recreate classic holiday films... after shock naked campaign

Sydney Sweeney is turning up the heat this holiday season.

A new advertisement for her lingerie brand, Syrn, pays tribute to holiday classics How The Grinch Stole Christmas, Home Alone, The Nightmare Before Christmas - but this latest campaign isn't exactly family-friendly viewing. 

The latest sexy campaign comes on the heels of Sydney's naked ad campaign for sports betting platform Novig.

But this time, she at least has some clothes on. 

In the new campaign, Sydney recreates scenes from the films as she models the latest sexy displays hitting clothing racks this holiday season. 

The advertisement begins with Sydney curling up on the couch with a bowl of ice cream in hand in a scene reminiscent from Home Alone before she clicks on the TV.

On television, Sydney appears to be channeling Cindy Lou Who from How The Grinch Stole Christmas as she puts festive decorations up.

Sydney has since opened up about her mission for the brand – insisting she wanted to ensure every piece fits well and works on a 'beautiful range of body types'.

SYRN aims to rival Kim Kardashian's Skims and Rihanna's Savage x Fenty.

Launching the brand, the actress explained: 'The secret is finally out... this is lingerie you wear for YOU, no explanation, no apology. I wanted to create a place where women can move between all the different versions of who we are.’

Sydney also holds an equity stake in Novig, the company she controversially went nude for in a new ad campaign. 

Sydney was one of the decision makers behind the lucrative campaign, which saw her pose completely naked with nothing but sports equipment to protect her modesty.

'It was a very exciting process to work with her both on the commercial side as well as on the creative side,' Novig CEO Jacob Fortinsky recently said.

'It really was Sydney who was driving a lot of the visuals and the messaging.'

Sydney echoed Fortinsky's comments, telling Complex: 'I've always believed that the best partnerships are the ones where everyone's getting to collaborate.'

She continued: 'I don't like to just put my face on something. I really want to be able to get into the weeds of it with an amazing team.

'Being able to be a part of watching this company grow and not just be the face of it is really important to me.'

After the ads were released, it emerged that the company's valuation ballooned from $500million to $2billion (£378M to £1.5B), according to the Wall Street Journal.

Sydney secured her stake in the company before stripping off for Novig's now viral 'Just Sports ad campaign.

While her share is unknown, even just 1 per cent is now worth $20million (£15M).

Despite the racy ad campaign going viral, Sydney lost more than 200,000 Instagram followers after it launched. 

It was slammed by many in the sports world, with several high-profile female athletes arguing that it made a mockery of women's sports.

'When we're trying to provide role models for young people and young women in sport, we really want to show that it's about what your body can do, not so much what it looks like,' British sprinter Amy Hunt told Good Morning Britain.

Australian boxer Skye Nicolson posted at the time: 'Giving the ad campaign exactly what they wanted, but honestly these companies need to do better. Stop sexualising women in sport.'

In the commercial, Sydney gets completely naked and uses a variety of sports equipment to cover herself.

'Think you know sports? Prove it. Novig is just sports,' she purrs.

Sitting naked on a basketball hoop, she continues: 'So they wanted a show? Just sports.'

Sydney, now wearing just shoulder pads and a football placed over her nether regions, adds: 'You can trade this sport. And this sport.'

'No betting on wars or deaths and no politics. Just you, your takes, and sports,' she later continues.

Novig is a prediction market app, similar to Polymarket and Kalshi, but it only allows users to make predictions on sports and nothing else.
