Fran, who is dating TOWIE co-star James 'Diags' Bennewith, took to Twitter after claiming her account had begun following 10 new users without her permission.
When one girl pointed out that they could be fans of hers, Fran hit back and told her where to go.
The spat happened after Fran posted: "Omg why [did] my Twitter just followed 10 random people, I'm so p*ssed off."
In response, one follower blasted back: "Why would you be p*ssed off? They're probz your fans .. Lol well not anymore after reading this."
Clearly unimpressed, Fran then fired off a reply saying: "I'm still following them you prat, just sayin it's annoying #boreoff." Ouch!
TOWIE returned to our screens with the first of a two-part Ibiza special on Wednesday night and featured scandal, tears and arguments.
Although Fran and Diags were briefly spotted dancing in a club in the episode, they were not shown speaking to their co-stars.
Meanwhile, the main storylines focused on Chloe Sims, Mario Falcone and Elliott Wright , Arg and Lydia Bright, Lauren Pope and Lewis Bloor, and Danielle Armstrong and James Lock.
Many viewers were left feeling particularly emotional after Danielle revealed during the show that she had suffered a miscarriage with James Lock's baby.
