Margot Robbie stuns in sheer look as she giddily talks about kissing hunk Jacob Elordi who admitted to 'mutual obsession'

Margot Robbie giddily discussed kissing her hunky younger co-star Jacob Elordi while appearing on Monday's episode of Jimmy Kimmel Live.

The Australian star, 35, sizzled in a sheer black lace dress while promoting her and the Euphoria actor's, 28, new romantic drama, Wuthering Heights, on the show.

The subject of kissing came up when Kimmel noted that there is 'a lot of sex' in the film, which is director Emerald Fennell's take on Emily Brontë's iconic, and only, novel.

'Is there that much sex in the book?' Kimmel questioned, to which Robbie replied that her character Catherine Earnshaw and Elordi's Heathcliff 'never even really kissed' in the novel.

'Wow, you guys do,' Kimmel cheekily replied. 'Yeah, we kiss a lot,' the Barbie star — who previously said she became 'codependent' with Elordi — concurred while smiling.

'All over the property,' Kimmel added, to which the blonde beauty said, 'We kiss everywhere, yeah, a lot of kissing.'

Robbie — who is married to film producer Tom Ackerley, 35 — went on to say that the movie coming out on Valentine's Day was a 'very intentional' choice.

The Oscar nominee shared that she recently watched the film with a number of her female friends.

'I would say like going with a group of girlfriends and having a couple of drinks, that's gonna be a fun night out.'

After she said that ladies can later watch the film with their partner, Kimmel joked, 'Right, and then on the way home you could say, "Why aren't you as romantic as Jacob Elordi?"' 

Robbie said she'd been thinking the same thing, admitting she worried women might begin comparing their boyfriends and husbands unfavorably to Heathcliff's decidedly less-popular rival, Edgar Linton, who marries Catherine. 

'I wonder if this will start fights, because I do think a lot of men are gonna turn to their partners afterwards and be like. "Am I Heathcliff to you or am I Edgar to you?"' 

'And I don't know if they wanna hear the answer,' she quipped. 

'And then the follow-up question's gonna be like, "Well then who is your Heathcliff?"' Robbie — who began shooting the film just three months after giving birth to her son — went on.

Kimmel admitted that he 'knew' he was Edgar, joking his wife may have even called him that. Robbie then stated that Edgar is 'such a green flag.'

It comes days after Robbie confessed to being 'codependent' with her co-star.

'I'm so codependent with people I work with and I love everyone so much and I'm always that person who's so devastated when a job's over and I never want it to end. I think I developed that quite quickly with Jacob too,' she said during an interview with Fandango.

'I don't know if Emerald told you to do this or you did this,' she said while addressing Elordi, 'but I remember the first couple days on set, he would just be always in the vicinity where I was, but like in a corner, watching Cathy.'

'I didn't tell him to do that,' Fennell, 40, chimed in as the cast laughed. 'I actually had to ask him to leave.' 

By the third day of filming Robbie said she found herself 'starting to look around to see where he was.'

When Elordi was not around, she said she felt 'really unnerved and unmoored. And I felt quite lost, like a kid without their blanket or something.'

Meanwhile Elordi admitted they have a 'mutual obsession' with each other.

The Frankenstein actor gushed that he made sure he was no less than 10 meters away from the Barbie actress 'at all times'.

'We have a mutual obsession,' he said during the interview, as Robbie sat nearby.

'I think the thing is, regardless of plot or screenplay, if you have the opportunity to share a film set with Margot Robbie, you're going to make sure you're within 5 to 10 meters at all times.'

'Watching how she drinks tea, how she eats her food, how she does it. When is it going to slip? When is the thing going to come undone? And, it never comes undone,' he added.

Elsewhere, the Saltburn star shared more behind the scenes secrets.

'There'd be a moment where we'd be running hand-in-hand through the moors – maybe not even in the scene, just setting it up – where I'd look across at her and she'd be looking at me... and in that moment, we really were a part of their love, for real.'

The film, which also stars Shazad Latif, Hong Chau, Alison Oliver, Charlotte Mellington and Owen Cooper, is co-produced by Robbie's LuckyChap Entertainment — the same company behind 2023 hits Barbie and Saltburn. She runs the company with husband Tom, with whom she welcomed a baby boy in October 2024. 

Wuthering Heights is set to hit theaters February 13.
