Summer alleged that three accounts which follow her are actually fake and run by Paul.
She shared her accusations on her Instagram story, sharing a meme of Leonardo DiCaprio raising a glass that read: “When you realise that your ex is stalking all your Instagram stories.”
Summer, 24, also listed the accounts she believes are run by Paul, penning: “Maybe you can stop looking at my Instagram stories on a daily through your fake accounts tagged below / @leigh_vardi / @chrisdavies31 / @i_feel_the_need_.”
She also tagged the song that was playing, rapper Cardi B’s Be Careful.
The next part of her story circled the account of Paul’s new flame, Melissa Spalding.
“And you babe!” Summer wrote, “@melissaspalding0909.”
Snaps recently surfaced in The Sun of Paul holidaying with Melissa in the same extravagant Cyprus resort he previously took Summer to.
They’re staying at the Hotel Annabelle in Paphos – where he met his wife Alexandra, who he’s in the process of divorcing.
A source told MailOnline that Summer reckoned Paul and Melissa had found a spark and struck up a romance prior to their split over the summer this year.
The source alleged that it was the reason Paul was so keen for her to sign an NDA stopping Summer from chatting about their relationship – reportedly a key factor in their breakup.
“Summer suspects this relationship is one of the reasons why Paul was keen for Summer to sign an NDA,” they said.
Sources close to Paul, however, slammed the idea.
They said: “Paul and Melissa got together in the last month after being friends for a while .
“He’s in a happy place and glad to have moved on with someone who courts less drama and respects his private life.”
Summer will be relieved that the rumours of her going Down Under for I’m A Celebrity have been put to bed, now that the series has kicked off.
Fans were sent into overdrive by a snap of her in a brown-belted minidress, with many translating it as a hint she’d be braving jungle life and the gruelling Bushtucker Trials.
Mirror Online has contacted representatives of Paul for comment.
