Maura Higgins is said to be plotting to make ex Curtis Pritchard 's life hell after his new romance emerged.
Maura and Curtis split in March, eight months after they coupled up on Love Island.
Rumours were swirling that Curtis had cheated with fellow professional dancer Amber Pierson, but they both denied that was the case.
But now that they've gone public with their new romance, with pictures of them kissing emerging online, some have become convinced that something was going on all along.
Maura, who was also hit with infidelity claims amid rumours she was growing close to her Dancing On Ice partner Alexander Demetriou - which they both denied - is said to be telling pals she's going to make Curtis' life hell after seeing the pictures.
A Love Island source exclusively told Mirror Online: "Maura is on the warpath and has been telling everyone she is going to make Curtis’ life hell.
"Maura has been with all the Love Island contestants and has been in touch with everyone this weekend seeing what we all think and telling us she’s going to make his life hell.
"She seems to not be able to move on and has been talking about Curtis for months and obsessing over who he is with and if he cheated on her.
"Someone dared to say to her about the rumours of her and her Dancing On Ice partner and she didn’t speak to them for weeks afterwards."
When the rumours about Curtis and Amber first emerged, he insisted they were just friends. They are thought to have become pals during Curtis' brother AJ's dance tour, which Amber was part of.
He slammed claims he was unfaithful to Maura, and Amber also said the reports were a "complete lie".
But new pictures have confirmed that they've since entered a romantic relationship.
Just hours after the pictures of Curtis and Amber emerged, Maura took to Twitter with the cryptic message: "The truth always comes out in the end."
In the images published by The Sun, Curtis wrapped his arm around Amber and leaned in for a kiss.
A source told the newspaper: "It's game over for Curtis and Amber pretending they are just pals. Their 'friends' line fooled no one."
Mirror Online has contacted Curtis and Maura's representatives for comment.
