In an exclusive interview with 9Entertainment, the Season 12 bride lifted the lid on Jamie and Eliot's post-experiment relationship saying they both "deserve" happiness.
"I think Jamie is in her love bubble at the moment with her and Eliot," Carina smiled.
"I think it's still early stages for them but they're definitely in their little happy bubble and enjoying each other's time together and really just getting to know one another," she confirmed.
Earlier, Jamie said she's in no rush to make things "official" with her co-star, but there's no doubt a close connection between the pair.
"She's just super happy and her old self again," Carina revealed. "There's a spark in her and they get along really well."
"I'm happy for them, she's deserving of it and he's deserving of it. If that's what makes them happy, then so it should be."
Carina revealed the three became close friends when Eliot was in Sydney post-MAFS with fellow grooms Adrian and Ryan. They had messaged her to catch up.
"When they came to Sydney a few months ago, we all caught up and hung out and that's when it kind of blossomed," she said of their friendship.
"We've all kept in contact, he's a really nice dude."
And despite having a tumultuous friendship during their time in the experiment, Carina revealed she and Jamie are in a good place.
"We had a good chat last week in the Gold Coast," she said. "We're back to being good friends."
Carina and Jamie's friendship was tested after she was caught in the confrontation that erupted between Jamie and Lauren at The Retreat.
Jamie felt betrayed however that Carina hadn't stood by her more strongly.
"I have no animosity against her, we're all human. We have different emotions and deal with things differently," Carina explained.
"She's in a really good place right now, I'm in a good place. We've rekindled our friendship.
"It's like the old days when we first started filming, you'll see how close we were, it's kind of like that all over again. It's really nice."
