The Love Island star is expecting her first child with fiancé Mark O’Connor, a former rugby player turned estate agent who she went public with in early 2021.

Montana recently showed off her huge diamond engagement ring as she shared an insight into her partner’s proposal.

The reality TV personality announced Mark had proposed to her during her exotic babymoon in April.

The happy couple’s baby boy is due to arrive next month.

In March, Montana announced her unborn baby’s gender with a touching Instagram video as they hosted a gender reveal at Huntlington House in Worcester.

The influencer could be seen beaming as she shared a clip of herself and her boyfriend Mark finding out the exciting news with their friends and family.

She had perfectly set the area with cushions on the floor with plates for lunch, as well as tables for drinks and gifts, and neutral gold and pearl balloons.

She stunned in figure-hugging brown dress which displayed her blossoming bump as she stood alongside Mark, who dressed casually in a black T-shirt and jeans.

Montana then took a pin and popped the balloon to reveal blue confetti before turning to hug Mark.

The couple then embraced and gave each other a kiss before turning to look at their loved ones.

Montana captioned her post: ‘Baby O’Connor is a…. gender reveal weekend at Huntlington House @uniquehomestays so grateful also for the beautiful decorations and set up by @twooakevents.’
