Irena then shared a photo from the season finale when Locky finally professed his love for her.
"For those asking our anniversary is the finale which is July 18th," she captioned it.
Back when they were on the show, Locky controversially told both Irena and runner-up Bella Varelis that he was in love.
In a recent Instagram Q&A, Irena admitted that she was a bundle of nerves before they filmed the season's final episode.
"The night before finale I was a mess which was strange because the moment I met Locky on the red carpet I knew it was going to be us at the end. My problem is my head, it thinks too much and overanalyses everything so I stressed."
The Bachelor winner also revealed some behind-the-scenes information about the day the finale was filmed.
"Also what you guys don’t see is that I got ready at 4am and this moment was at 5pm. So waiting all day stressed me out even more, so much so that when Locky said it was me I was in shock for a few hours.
"My heart knew, with each moment that we spent together I knew that he was my person and he was my soulmate."

Both Irena and Locky have made no secret that marriage and kids are on the cards for them.
The couple are currently travelling around Australia, and have admitted that they can't wait to share the memories with their future kids.
"We have spoken about getting engaged, pretty much planned our next 5 years already and we would love to have some babies," the nurse turned reality star said on Instagram.
