Heidi Montag is pregnant with her second child, with husband Spencer Pratt.

The Hills star confirmed the news in a new interview, revealing that the couple are set to expand their family once again.

The 35-year-old, who already shares son Gunner Stone with her former co-star, 38, also spoke of their struggle to conceive beforehand, leading to drastic changes in her diet.

‘I couldn’t be more excited. I don’t know who I’m the most excited for – myself or Gunner or Spencer,’ she said of the news. ‘I just felt like something was missing. I felt like a person was missing in our family that I had this intense love for. 

‘And I kept praying about it. I’m like, if I’m not meant to have another kid – because I had accepted that at this point – I just wanted to not have that desire so strongly and I just wasn’t sure if it was going to happen or not. I just get so emotional about it.’

The happy couple detailed that it had been a ‘rollercoaster’ journey to get pregnant for a second time.

‘I think a lot of women struggle with this and it’s just not something a lot of people talk about because it’s so hard and it’s so personal,’ she continued to Us Weekly. ‘And I felt really blessed having Gunner and having such a beautiful healthy son, so I was trying not to be ungrateful for my life and for what I do have.

‘And at the same time, it was such a deep longing in my heart that I had – wanting a sibling for Gunner and wanting to expand our family.’

Heidi shared that they had been trying for ‘about 18 months’ before she learned that she was pregnant for the second time.

At one point, pal Brody Jenner reportedly offered to pay for IVF treatments in a bid to help the couple add to their brood.

The Laguna Beach alum added that it will be a ‘big adjustment’ for the family, who will be facing ‘different challenges and some nerves’ as they prepare for the new arrival, who is due in December.

Heidi and Spencer famously met while filming the Hills, in 2006, and eloped in 2008, before tying the knot once again – in front of the cameras – the following year.

They have been inseparable ever since, and welcomed son Gunner in 2017.

Heidi went under the knife last year for a hysteroscopic polypectomy procedure, in a bid to conceive once again.

The surgery aims to remove polyps, which are non-cancerous growths in the womb, and normally takes between five and 30 minutes. 

Detailing the operation on YouTube, in a video titled ‘Heidi gets surgery to help her get pregnant’, she told viewers: ‘I was feeling nervous last night about it, but I’m excited today.

‘And I hoping that the surgery works and that this is the only reason I haven’t been able to get pregnant.

‘Hopefully after this I can get pregnant, I am just reflecting, think it’s the perfect timing and meant to be.

‘And so thankful I didn’t have other problems and complications from this.’
