She's set to celebrate a huge milestone on New Year's Eve.

Yet, while being interviewed by the podcast Wake Up By Taylor on Wednesday, Luann de Lessep confirmed that neither Bethenny Frankel, Sonja Morgan, and Ramona Singer have so far received a Save The Date for her own wedding.

'I would say they're not invited for the moment,' Luann, who is to wed Tom D'Agostino, told host Taylor Strecker of the ladies, hinting things could change.

She insisted, however, there was a difference between a Save The Date versus an actual invitation.

'I have not sent the invites out yet,' Luann said of the actual invitations. 'I've sent Save The Dates out.'

The reality star also acknowledged that Dorinda Medley and Jill Zarin had received Save The Dates.

'And Jules and Carol, their invitation status is unknown, allegedly,' host Taylor added, 'and you've said you're gonna see how they behave. I think that's totally fair. '

Meanwhile: Taylor then broached Bethenny (pictured in June in New York) and Carole Radziwill's (pictured in August in New York) attention on Jules Wainstein

'No, I don't have a problem with Carole or Jules,' Luann insisted.

Taylor then broached Bethenny and Carole Radziwill's attention on Jule Wainstein's weight.

In a previous episode, the ladies partook in a cooking class with Jules, where she talked about her past struggle with eating disorder.

'She's f**king crazier than I thought,' Carole said after Jules jokingly considered sprinkling hers with Lidocaine.

Speaking out: Jules, pictured in August in New York, would go on to reveal that she had actually suffered from an eating disorder before seeking treatment in her early 20's

Bethenny, in a past episode, said Jules 'looks like a really thin girl…she looks like there’s an issue,’

Jules would go on to reveal to People that she had actually suffered from an eating disorder before seeking treatment in her early 20's.

'We're talking two other very thin women going after another thin woman. I'm sure people have questioned Bethenny's health,' Taylor said.

Luann then brought up the infamous photo Bethenny posted of herself in 2014, clad in her four-year-old daughter Bryn's pajamas.

'And she's gonna talk about Jules being too thin, I mean give me a break,' Luann said.

'I feel like that when somebody has a problem, that to be picked on is certainly not the way to help them,' she added.

'So I disagree with them dissing her on her weight, and kind of not being more aware of it, and what's the word I'm looking for, sympathetic towards her. So I didn't like that.'

Luann is to wed Tom on New Year's Eve.

She revealed during her appearance on Wednesday that she would be sporting a total of three different dresses on the day of her wedding.

'The traditional one, the one where I might sing a song for him, and it's New Year's Eve, so it's time to ring in the New Years,' she said, before adding: 'The end of the night dress is just very - it's a bit revealing, with some bling. Elegant at the same time.'

Luann and Tom became engaged in February after nine months of dating.

While Luann's fiance has previously had a fling with Sonja and also dated Ramona, the reality star is focusing on their relationship now.

'What's Ramona's story line, what is Ramona talking about?' Luann asked aloud as she spoke about how the the reality show focused on her relationship, rather than the other story lines unfolding on the show.

'Nothing, except how she would have loved to date Tom more. And Sonja, poor thing, is like, "Oh. What about me? I like Tom." It's so pathetic.Tom has previously had a fling with Sonja and also dated Ramona, but Luann is

'Because, look, I'm getting married to Tom. And like I say, look, I understand, Tom is 49 years old, he's a bachelor, never been married, alright? He has past. So do I. But guess what girls? You're in the past. I'm his future.'
