Controversial Married At First Sight star Brook Crompton has revealed the gender of her baby in a sweet video.

Brook, 27, was partnered with Chris Neild, but shocked viewers when she walked away after just three weeks, amid speculation that she had reconnected with her ex during the experiment.

Shortly after her exit, Brook reunited with her former partner, Harry, with the couple now engaged and expecting their first child.

Brook, who has kept a rather low profile since her shock exit from MAFS, took to Instagram this week to give followers an update on her life.

Leaving her reality show drama behind, Brook shared an intimate montage video that showed her off-camera life with her fiancé.

The video showed major milestone moments in Brook and Harry’s rekindled romance, including the moment he got down on one knee during a vacation in Aspen, Colorado.

The couple were also shown looking very loved-up during a post-filming Maldives getaway.

The montage also included a sonogram video of Brook’s precious cargo and clips of the reality star showing off her burgeoning baby bump.

Harry was also seen doting on his child, leaning in to gently kiss Brook’s growing tummy.

Captioning the video, Brook revealed that she and Harry were expecting a baby boy.

‘To our little boy, you’ve already filled our world with so much hope and love,’ she gushed.

‘The past year, and especially these last few months, have taught me more than I ever imagined about patience, love, and the person I want to be.’

Brook continued: ‘I’ve dreamed of being a mother for as long as I can remember, and sharing this journey with the person I love most makes it even more special.’

She then turned her attention to Harry, paying sweet tribute to the 28-year-old builder.

‘Harry, you are my rock, my safe place, and my heart. Thank you for making my dreams come true and for showing me what family truly feels like,’ she added.

‘I can’t wait to watch you become the father I know you’ll be – kind, strong, and full of love.’

Rounding out the post, Brook shared her excitement at becoming a mother for the first time.

‘Baby boy, we are waiting for you with full hearts. You’ve already changed our world in the most incredible way,’ she wrote.

‘We can’t wait to meet you, hold you, and begin this next chapter of our lives together.’

Daily Mail recently confirmed that Chris and Brook had called time on their relationship, with Brook later rekindling things with her former partner.

After weeks of mounting speculation, Daily Mail also revealed that Brook was the bride accused of secretly reconnecting with her ex while still part of the experiment, and was pregnant.

In footage obtained, Brook is seen kissing her ex-boyfriend Harry as the pair decorate a Christmas tree together in October – just weeks after her on-screen marriage to Chris came crumbling down off-camera.

‘To our little boy, you’ve already filled our world with so much hope and love,’ she gushed. ‘The past year, and especially these last few months, have taught me more than I ever imagined about patience, love, and the person I want to be.’

She added: ”Harry, you are my rock, my safe place, and my heart. Thank you for making my dreams come true and for showing me what family truly feels like,’ she added. ‘I can’t wait to watch you become the father I know you’ll be – kind, strong, and full of love’

The intimate video shows the couple unable to keep their hands off each other, sharing several kisses and cosy embraces inside an apartment as they put up Christmas decorations weeks before December had even arrived.

Multiple cast members told Daily Mail that Brook and Chris never stood a chance.

Meanwhile, her ‘husband’ Chris has turned to dating apps following his brutal split from Brook.

The 31-year-old construction supervisor from Victoria has a profile on Raya – known as Tinder for celebrities.

He is also using the popular dating app Hinge, where he describes himself as a ‘carpenter’ and shares an image of himself wearing a tight singlet on his profile.
