Earlier today, Kirk took to Twitter to share a snap of himself and his wife-to-be with followers and the reality star can be seen beaming from ear-to-ear.
Alongside his photo, the 27-year-old couldn't resist gushing over Holli, tweeting alongside it: "MY WORLD."
In his snap, Kirk is pictured looking oh-so-dapper in his checkered shirt, wearing a huge smile across his face. Next to him, Holli looked just as happy to be cuddled up to her beau.
The couple, who rekindled their romance shortly after Kirk's stint filming for Ex On The Beach, have seemed nothing but loved-up since reuniting.
So much so, that it didn't take long for Kirk to pop the question, with the pair confirming their engagement last month.
As well as being headed for the aisle, Essex boy Kirk is heading for parenthood too.
He and Holli are expecting their first child together, a baby girl. Revealing his exciting news, Kirk shared a photo of their baby's scan to social media, telling fans finding out he is going to be a dad was the "proudest moment" of his life.
Kirk said: "Everyone meet mine and Holli's little girl!!! Proudest moment of my life so far!"
And preparing for their daughter's arrival, the couple have been busy putting together her all important wardrobe. Kirk tweeted earlier: "Just purchased some new clobber for my little princess."
