On Sunday night's series 18 opener, The Only Way Is Majorca, viewers saw Lydia and Arg come face to face for the first time since their split earlier this year.
Lydia made it clear to Arg he wasn't getting any further chances with her and told him she didn't want him in her life anymore.
That led to some criticism of Lydia being too harsh.
But she's now fought back, tweeting: "Really frustrated by today's press. Yes I was harsh & some people have expressed that but equally I have received so much support from viewers. Everyone is entitled to express views on the situation. However highly frustrating when press are only printing the views against me."
Lydia's tweets received plenty of comments from fans, some of whom completely backed her up, while some others thought the conversation should have been had off camera.

Lydia and Arg quietly split after series 17 wrapped filming in March, only making the break up public several weeks later. No official reason for the split has been given other than Lydia saying she'd been hugely let down by Arg just when they had been planning to a house and invest in their future.
On Sunday night's episode, Arg told her he was sorry for what had happened, adding: "I do absolutely adore you. You know how much I love you."
Lydia told him: "When I look at you, I'm angry but I feel really sad for you. You had everything you ever wanted: you got me back after all those years, we were getting a house, we were getting engaged, but nothing was ever good enough for you.
"I just think moving on from now I deeply don't want us to ever be friends. You're not the kind of person I want to be in my life."
