Australian star Jai Brooks has blasted out at Nickelodeon star Ariana Grande on Twitter claiming that she cheated on him with Nathan Sykes.

"Yes I was cheated on. Yes it does s**k. Yes I was left for another man," the 18-year-old wrote in an extended tweet, "And this happens everyday to so many people of every age, gender, race. I happen to be one of those people and I'm in a situation where I am constantly reminded of it every day. Like anyone who has been cheated on, it has been tough for me but I'm finally ready to move on."

"Once you are cheated on you should never go back and I did because I wasn't ready to give up on love and something that was everything to me. I wasn't ready to give up on something that was causing me to smile and be happy day in and day out. That's what relationships do, they make you the happiest person in the world and all of a sudden a miserable wreck. That is why if you know someone who is in a relationship, I'm begging you to please not interfere with that, because you are going to destroy someone and crush their world."

"Nathan may be a top bloke or a sweet person, but what he did was just completely wrong. He interfered with my life and did not respect my relationship, his actions caused me to not be able to sleep at night and not see the world as a beautiful place. Nathan if you read this, when you hold her hand you better hold it tight because you are holding my world. I do wish you two happiness and a good life and hope everything works out. Through all of this I have been able to mature as a person and grow up and have learnt a lot about myself. I have learnt how to find happiness on my own without relying on anyone else. I'm not going to go into the full story of what happened because it isn't anyone else's business and I'm just not ready to. Today was supposed to be our one year anniversary but instead I'm writing this," the Janoskians performer added.

The 20-year-old Victorious actress responded in a series of tweets, writing, "You said to me if I didn't come back to you, you'd make me look bad to the entire world... I'm no longer afraid of you or your lies anymore."

"I'm going to be the lady my mother raised and carry myself with class and dignity... But I will never be any man's press opportunity," she continued, later adding, "I'm finally happy. Words can't hurt me anymore."
