The dancer was greeted by boos as she became the fourth contestant to leave the Big Brother house.
Asked by Brian Dowling why she thought she had been voted out, Lydia replied: "To be honest, I think I always expected it, I have to be honest.
"I thought coming on here, it was a massive risk for me. And I knew that just having someone who was in the public eye as a partner, and the stuff I'd done before, I know that some people... sometimes they don't like that kind of stuff.
"I just wanted to represent people my age that are successful or whatever."
When asked to elaborate on why Deana Uppal had been saved over her, she said: "I can't second-guess it, I've not seen it."
She went on: "I got saved once and I'm chuffed with that. I could have been gone in the third day.
"It would have been awful... For me, it's like, I've lasted nearly a month."
Lydia then clarified: "I am happy to be out, I was having a really hard time in there this week."
When asked whether viewers had seen the real Lydia, she replied: "I don't think you can be the real person in there. You try to be, but because it's so... intense, and because, you know, things are petty and you get, you know, it's not how you would be on the outside world."
After being shown footage suggesting that she had been plotting, the evictee explained: "I will always be perfectly honest, and because I got up in the first three days I knew I was an easy target and from then on it changed my thought process in there. I didn't feel like I could relax."
She said that she would remain friends with Benedict Garrett, Luke Anderson, Adam Kelly and Lauren Carre, adding that Sara McLean is a "lovely girl", but claimed: "The others were plotting and I felt like I had to do the same."
After denying that she had been trying to step out of Scott-Lee's shadow, the interview ended with Lydia hugging and kissing her fiancée while Brian Dowling assured her that the wedding was "still on".
