Pregnant Lindsay Hubbard explains why she's protecting the father of her baby's identity... after she confirmed her ex Carl Radke is NOT the dad

She shocked her fans by revealing that she was pregnant with her first child last week.

And Lindsay Hubbard has since kept them guessing by opting not to reveal the identity of her baby's father, who is apparently her current partner.

However, she did make it explicitly clear that her former fiancé, Carl Radke, was not the father of her child. 

Over the weekend, the 37-year-old Summer House star explained to People why she is staying mum about the upcoming child's dad.

She revealed that her boyfriend had asked her to keep him out of the spotlight, particularly as she begins filming season nine of her Bravo reality series, despite being 'so excited' about the prospect of sharing a child with her.

'He's a private person, mostly because of his high-powered job,' she explained, after previously revealing that her new love is a doctor who works in biotech investing.

Although her partner's face wasn't seen, his hands cradled her stomach in the photo, while she rested her more delicate hands on his.

'Obviously, I'm a very public [person] and share pretty much every aspect of my life with the world, so I know it's weird,' she said of the couple's desire to stay under the radar. 'But I need to respect his privacy here.'

While she has offered few details about about her boyfriend, Lindsay appears to have first mentioned him during the season eight reunion for Summer House, when she revealed she was dating 'a wonderful man.'

She revealed at the time that the were taking their second stab at love, as they had previously dated 'three-and-a-half years ago.'

It's not clear how long the first attempt at a relationship lasted, but Lindsay and her mystery man started dating again in December of last year. 

'I would say it's tracking in the pretty serious direction,' she said during the reunion. 'He’s been a great support.'

What Lindsay didn't mention at the time was that she knew she was pregnant while filming the reunion — and her boyfriend knew he was going to be a father as well.

She explained that they had learned a few weeks earlier when she took a test. 

'Obviously, it was a surprise and a shock at first because we were not trying or even planning, but we had some honest conversations and it just felt so right for both of us,' Hubbard says. 'He's just so excited to be a dad and proud to be having a child with me. It just means the world to have someone like him by my side.'

'He's a private person, mostly because of his high-powered job,' she said, explaining that he asked to not be involved in Summer House

Part of what made it feel like the right time was how safe she felt in their 'very loving, caring and healthy relationship.'

'He's a really loving man. Sweet and nurturing and understanding,' she gushed of her mystery man. 'He's highly emotionally intelligent. He's probably one of the smartest guys I've ever met, and really handsome, of course.'

'I finally feel like I met my match with him,' she continued. 'And yes, it is a lot of pressure on a new relationship, but I think because he's the right man because we are so bonded and connected and communicate very effectively with each other that it hasn't felt like work.'

She added, 'You know, I've almost made terrible mistakes in my past because of a biological clock that we naturally as women have, and this is the one time where it just all feels so right. I'm just so lucky that the universe put us back in orbit of each other.'

Earlier in June, the star discussed the complex aftermath of her canceled wedding to Radke, and how much money she lost in the process.

Lindsay spoke about having to get lawyers involved to sort out the bills the exes still owed when she appeared on the Not Skinny But Not Fat podcast last month. 

She said that she specified to their wedding planners that it was Carl's job to take care of canceling the event. 

'I texted my wedding planner and the two wedding planners — like, one who was dealing with the hotel and reservations and one who was dealing with all the vendors and actual planning — and I said, please do not communicate with me about any of this,' she said. 

'I told them that I was absolutely not figuring out the fallout of the wedding. Like, you canceled this, put on your big boy pants and figure it out yourself.' 

She told her planners: 'You can communicate with Carl since this was his decision. And whatever he did, that’s on him.' 

Lindsay said she lost about '$25,000 to $30,000 in wedding deposits before the cancellation.'

'Now, he had to pay a lot of cancellation fees, especially since he waited so long to call off the wedding. And, you know, the longer you wait with the hotel and the rooms, like, the less money you get back if you cancel the wedding,' she added.

The star shared that once the ceremony is 90 days out 'you're responsible for 50 percent of the rooms.'

She was then asked if she wanted Carl to pay her back the money she lost, to which she replied, 'Yeah, we dealt with a lot of... There was a lot of lawyer discussions.'

Last month, Lindsay revealed that she and her ex Carl had to get lawyers involved to help divy up bills from their canceled wedding; seen in Santa Monica in June 2022

Last month's explosive Summer House season eight finale unveiled how the pair's engagement came to an end last year.

The two reality stars intended to tie the knot in November 2023, before Radke called off the wedding in late August.

Fans were able to watch it all unfold during the former couple's breakup conversation on the latest episode of the series.

Lindsay started the exchange by stating, 'I do not want to fight with you. It's not productive, it's not helping either of us. Today I was like, "Oh, maybe Carl sees me asking questions as me belittling you or thinking you're not capable." And then I was like, "But where did this come from?""

But following a summer ripe with friction, Carl confessed his wish to nix their wedding plans.

He cited Lindsay's ongoing discouragement as she shot down his various career goals, including his hopes to focus on acting and to open a sober bar.

'I have asked for you to be a little more comforting and excited and positive, versus the questioning,' he explained.

The television personality also called out their disconnect.

'I literally live in two different worlds with you,' he emphasized.

'There's the reality and then there's what you spin the reality to be. You're really gifted at playing victim,' he told his then-fiancée.

Additionally, Carl named the hurtful things Lindsay had said leading up to their final conversation.

'Time and time again you're over-questioning, you bulldoze me, you called me a loser,' he listed.

'You called me a little b***h, you called me a little baby, little mama's boy — "run home to your parents."'

He then turned the discourse to his sobriety journey, admitting that he believed Hubbard was rooting for his downfall.

'I don't think you trust me,' Carl went onto say.

'I think you think I'm gonna relapse. I think you want me to relapse. I think you want me to fall back so you can control me even more,' he unleashed.

The social media star added: 'We continue to trigger each other and I don't want to live like that.

'We are supposed to be married in two and a half months and I'm not ready to do that. I don't feel comfortable. I'm hurt, I'm really unhappy and I don't think our communication is going to improve.'

Lindsay fired back, 'You want me to fight right now for this relationship? I'm not gonna beg you to be with me.

'There's no more point to this conversation, you've made the decision clear.'

While she called her father to vent in another room of their NYC apartment, Carl chatted with producers. 

In the season eight finale, he said their fights had gotten so bad that they received a noise complaint from their apartment building

'I can hear her conversation,' he told someone off camera. 'It's like "all of a sudden."

'No, this isn't all of a sudden. That's the crazy part. She's blind to the things that have gone on the last year. Fight after fight after fight.'

'Even in this building we had a noise complaint because of our fighting and she got an email from the landlord,' he revealed.

He expressed feeling like he's 'always gonna lose' with Lindsay. 'She's gonna spin and tell everybody she's blind-sided, she's caught off guard and I'm gonna be the a**hole again and my life will be canceled. But she'll be the fallen woman who everyone's gonna feel sorry for.'
