Marnie announced her pregnancy in February with a black-and-white video featuring her ultrasound and touching moments of her children cradling her bump.

Fans were shocked by the news, as Marnie had previously insisted she wouldn’t have a third child due to her past difficult pregnancies.

When pregnant with her second child, she stated: ‘I would not go to three. I think you’ve got to find the balance for yourselves.

‘We want to enjoy our lives as well. We’ve not waited too long to have kids and I feel like having two, we can give them the best life possible.’

Casey and Marnie first became an item in June 2017 after they appeared on the reality show, Single AF together. 

Marnie previously revealed she was ‘shocked’ when Casey proposed in 2020 because she was ‘at her worst’ both ‘mentally and physically.’

She said she couldn’t believe the former X Factor singer wanted to marry her after she spent months suffering from a painful bladder condition.

Marnie was diagnosed with a chronic UTI in 2016 which got worse after giving birth to Rox in 2019.

The reality star revealed she had to spend ‘thousands of pounds’ on doctors’ consultations’ she was eventually diagnosed with Trigonitis in 2020.

Trigonitis is a condition where the triangular piece of tissue located in the lower part of the bladder becomes inflamed.

Speaking about her engagement, Marnie told MailOnline: ‘It was a really emotional moment because I think there were times this last year that I just couldn’t even believe Casey was staying with me.

‘I was in such a bad way mentally, emotionally and physically; I couldn’t believe he even wanted to be with me. I was in such a bad way.

‘When he asked me to marry him I was honestly shocked because I thought ‘you’re asking me to marry you when I’m literally at my worst?’

‘For him to ask me to marry him at that point I thought ‘what? You’re asking me to marry you when I’m this ill?’ It completely shocked me. He said he loved me unconditionally and it was just a real special moment.’

Marnie rose to fame on Geordie Shore alongside co-stars Charlotte Crosby, Holly Hagan and Sophie Kasaei, where she was filmed having sex on TV, stripping off and having bust-ups.

While Geordie Shore is still going, it now has a much different feel, with many of the cast members married with children.

The latest season saw Marnie, Abbie Holborn, Chantelle Connelly, Charlotte Crosby, Chloe Ferry, Holly Hagan, James Tindale, Jay Gardiner, Kyle Christie, Nathan Henry and Sophie Kasaei travel to Cyprus with their partners and kids.
