However, one former Bachelor contestant doesn't believe the pair will last for one huge reason.
Speaking with Hit's Jimmy and Nath on Thursday, Maddy Carver said she "can't see them getting married".
"Locky had all these girls’ attention inside the mansion," she said.
"It would be really hard to go back to life just having one girl, don’t you think?" she added.
Maddy's prediction comes after Locky called Irena is "future wife and baby mumma" on Instagram.
His entire statement read, "I have always listened to my heart and it has lead me to this point. As hard as it was to say good bye. I was also saying hello to my future wife, baby mumma and best friend.
"I cannot wait to spend the rest of my life with you. Here is to one crazy adventure and so so many more with you babe."
Maddy did have lovely things to say about Irena, however.
"I honestly don’t think Irena has a bad bone in her body. She was the mother of the house. She was the one that was cleaning, she was the one that was cooking," she said.
"The nights that some people didn’t feel well she’d be ‘nurse Irena’, and she’d get out her medical kit … giving people Panadol if they needed it."
Maddy also revealed on the show that she's "loved up now", revealing her man is someone she's known for some time.
"We’ve known each other for about six years and went on a date six years ago. We didn’t click at all, and then [we] caught back up and this time something just clicked, and it just feels right."
Speaking with Who, Irena revealed she would be moving from Melbourne to Perth, saying that Locky wasn't all that keen on moving to her home town.
"It was a hard sell for Locky to move to Melbourne with COVID at the moment. I really did not have Melbourne on my side so we made the decision that I would be moving over to Perth and I can’t wait to get over there," she explained.
She added that she doesn't see herself being with anyone else for the rest of her life.
