Lydia quit the reality show at the end of 2012, but made a surprise return at the end of series 11 in April 2014. Despite some ups and downs with childhood sweetheart James 'Arg' Argent, they're now back together for good.
"I have no regrets," Lydia said on ITV's This Morning. "Not at all for me personally, I've absolutely loved it. We've had amazing lives and got to do and experience amazing things, and meet great people. Overall for me, I always pinch myself still and think about how lucky I am and the experience we've been through."
Lydia appeared on the ITV daytime show alongside Arg, Chloe Sims and Jake Hall to talk ahead of the brand new series returning on Sunday.
Speaking about the popularity of the show, Lydia said: "All of us from our experience of being on TOWIE have all used it to our advantages. We've set up businesses and become young entrepreneurs and I think we've made the business boom in Essex. A lot of the shops down our high street all say to us, 'thank you, it's brought so much tourism'.
"We're all really proud to be from Essex because what we show is really hard work ethic. We're just down to earth, normal people, trying to make a good opportunity even better and just be successful with it. I'm proud to be from Essex!"
It was revealed last week that TOWIE has been commissioned for a further six series, meaning it will run until the beginning of 2017.
Lime Pictures' Derek McLean, said: "We are so thrilled to announce we have been commissioned for six more series of TOWIE. It is not only the leading show for ITVBe, it is a huge priority for ITV in general.
"We want TOWIE to become an ongoing, real-life soap opera," he continued. "It is just as important to ITVBe as Coronation Street or Emmerdale are to ITV."
TOWIE first aired on ITV2 in 2010, and moved to brand new sister channel channel ITVBe in 2014.
The Only Way Is Marbs, Sunday 14 June at 10pm on ITVBe.
