The reality TV star, 26, took to Twitter on Saturday (23 April) appearing to defend herself after a dramatic week.
In a series of heartfelt tweets, she began: "A few things need clearing up.
"I do not attack friends for no reason. Before *that scene* she threatened to talk sh*t about James and I if I didn't 'have her back'.
"So yeah, I lashed out. And she came true to her word. #thingsyoudontsee."

Lucy also posted a quote, which read: "One fake friend can do more damage than five enemies."
On the last episode of Made In Chelsea, which aired on Monday 19 April, Lucy said she could never trust Steph again.
Viewers watched the start of Lucy and Steph's fallout in the episode, with Lucy being unimpressed at Steph's previous "cute" comment about Alex Mytton.
However, the spat soon escalated as Stephanie involved Lucy's relationship with James Dunmore, insinuating the pair were having troubles.
Not true, says Lucy.
After the fraught episode aired, the pair had a very public Twitter row where Lucy told her former BFF: "I don't want to hear from you anymore."
Stephanie has not responded to Lucy's most recent Twitter posts, however she did recently thank her fans on Twitter for their support.
She said: "Love you guys... It's been a sh*t few months for me. This support really means a lot thank you."
We'll have to wait until Monday's episode to see what happens next!
