The reality TV star branded the girl "an absolute lying tramp" after she tweeted Wright claiming that Rayment had been spotted cheating during a holiday to Ayia Napa by some male workers.
"That Is absolute bull s**t!! I was never with anyone at all except my manager," he wrote. "Nothing better to do than pass on rumours that you've heard, ur an embarrassment.
"Tell these mystery boys... to come and tell me? Cos ur lying and so are they...f**k the haters! Your s**t on the bottom of my shoe...go sort your lives out before u comment on mine #tramps."
He added to the young user: "Ur nothing ur the sort of girl people Look at and feel sorry for...u can say what u like...u have no proof of anything...u wasn't even there u just spread a rumour uve heard."
Rayment then tweeted the girl's profile picture along with the message: "What an absolute troll! Vicious girl who likes spreading rumours...not to be trusted definitely not to be followed."
When she asked why he was "getting so aggressive" with a woman, the TOWIE cast member responded: "U are far from what I would call a woman... Your a man dressed up as a troll."
Wright recently claimed that she and Rayment are "not interested in being the show's biggest love story".
