Emily Ratajkowski smokes a cigarette as she goes braless in a daring cut-out red dress while celebrating at her 35th birthday party

Emily Ratajkowski puffed on a cigarette and sizzled in a red cut-out dress as she posed for snaps while celebrating at her 35th birthday party in new images shared on Monday.

Giving her fans a glimpse of the celebrations, the model shared a number of snaps to Instagram, with the images seeing her showcasing her physique in a skin-tight dress.

The eye-catching red number featured a daring crochet-style cut-out at the front, with Emily potentially risking a wardrobe malfunction by opting to ditch her bra.

The brunette stunner teamed her outfit with a jazzy pair of animal-print heels, while she left her locks to cascade down her shoulders.

Emily was clearly in a party mood, with a clip seeing her enjoy a smoke, while other pics saw her with a tipple in hand.

Joined by her nearest and dearest, the star beamed as she blew out the candles on her enormous red birthday cake before dancing the night away.

Thoroughly enjoying the festivities, images also showed Emily flaunting her toned legs as she kicked back outside the venue.

Emily's birthday celebrations comes after she unveiled a sultry new look on Instagram last month.

The model drew attention to her doe eyes by rocking green-hued color contacts.

She wrote in the caption to her 28 million followers, 'almost scratched my eye out getting these out but…worth it :)'

In addition to the fresh eye color, the beauty also flaunted soft brown freckles speckled across her cheeks and the bridge of her nose.

Emily tagged makeup artist Zahra Redgrave, who revealed the transformation took place for Gucci's Cruise 2027 Show in New York City on Saturday.

Fellow model Alex Consani also appeared in the star's carousel post. 

It comes after the California native posed in underwear as the fashion house debuted its Giglio tote bag campaign in March.

During that time she spoke to Harper's Bazaar about the launch, sharing, 'I actually really love it. 

'I am of an age where I love to carry a big bag – and I just think Gucci’s version is timeless and cool. It makes so much sense to me how Demna is approaching these styles.'

And the mom of one, who shares five-year-old son Sly with ex-husband Sebastian Bear-McClard, added, 'In my bag right now, I have my son's toys, I have snacks, matches.' 

Elsewhere in the conversation, she spoke about her connection to the luxury brand.

'This has been such an organic, natural development of a relationship. There are a lot of days you think, “Okay, I'm going to be a Gucci girl today,” but this just feels really aligned with who I am and how I dress and what I represent, which is super rare,' said Emily.

She went Instagram official with Romain Gavras – who used to date pop star Dua Lipa –  in February.

Days after Valentine's Day she shared multiple loved-up photos with Gavras, 44.

The carousel post, which included a snapshot of the couple cozied up at a dinner table, did not include a caption.

An image captured on film showed the filmmaker clutching Ratajkowski's head and wrapping his arm around her while she wore a backless LBD.

The couple were first romantically linked last November, when they were spotted kissing in New York City.

This appears to be the iNAMORATA swimwear designer's longest romantic relationship since her divorce from movie producer Bear-McClard in 2022.
