LOVE Island's Lucie Donlan gets a shock when she meets new girl Arabella Chi on tonight's episode, gasping: "I've stalked you."
The 21-year-old surfer, who is still reeling from the brutal dumping of boyfriend Joe Garratt from the villa, is confronted by her ex-boyfriend Charlie Frederick's former lover.
Lucie and last year's Love Island star were a couple for six months - before they broke up and 28-year-old Arabella dated him.
Viewers tonight see the newbie being given a grand tour of the villa, only for the pleasantries to turn to awkwardness when she meets Lucie on the stairs.
Spotting her instantly, the heartbroken Islander says: "I recognise you. You’re my ex’s ex. I’ve stalked you before.”
Arabella, who has vowed to break up the couples if she needs to, admitted before she went in that she and Charlie used to be an item.
She makes her appearance in the villa tonight by draping herself over a sun lounger and waiting to be noticed by a stunned Curtis Pritchard.
Meanwhile, Maura Higgins is positively fuming to have yet another beautiful love rival to deal with.
The 28-year-old fumes: "Banging body. Now that gives me f***y flutters. Great hair. More competition for Maura!"
Reflecting on her arrival in the Beach Hut later, Arabella says: “I feel like they’ve warmed to me really well. Obviously, I’m going to have to tread on toes and I want to find love. That’s the goal.”
Charlie himself waded into the drama today - insisting he was dating Arabella before she went on the show and - using perfect Love Island vocabulary - complained he had been "mugged off".
Addressing his social media followers, Charlie said: "Right so this is an absolute madness for me.
"Finding out that a person I'm seeing on a serious level has just strolled into the villa completely disregarding my feelings and our relationship or what we had.
"I feel like I have to air these screen shots because I feel like I've been completely mugged off.
"I'm truly upset that Arabella has lied to me about what she was doing and claiming she had a campaign but instead actually going into Love Island.
"Every relationship has its ups and downs but these next screen shots are all within the last 2 weeks. I'm truly gutted and for the life of me cannot figure out why she has DONE THIS."
Charlie then shared WhatsApp messages of conversations between the pair in which Arabella begs Charlie to come over to her house.
In later messages, he asks her why she has ghosted him, and eventually calls her a "headcase" and "so f***ed up".

One message from Charlie said: "I don't understand why you've ghosted me really doesn't seem like that's all it is.
"Thought you'd had your phone nicked or something all you had to do was text saying I'll ring you in a few hours? But you just kept reading and not responding why would you do that."
Arabella apologises for treating Charlie like 's***'
But in other messages between the pair, she insists "I need you in my life" and apologises for being a "mind f***".
In another Charlie says he's tired so can't go over to her place, she replies: "I just want to hold you and be in your arms. please babe x I'm actually begging you."
Then Charlie repeatedly calls her out for blowing hot and cold, and she replies: "I know that baby, and I wouldn't normally expect you to come round at the drop of a hat.
"But when you see me you will realise how much I need you right now."
