Ariana Grande Set Up By Jai Brooks, or Did 'The Way' Singer Cheat with The Wanted's Nathan Sykes?

Ariana Grande's ex-boyfriend Jai Brooks recently posted an open letter on Twitter accusing the Sam and Cat star of cheating on him. Now it appears that "The Way" singer is being set up by her bitter ex. Meanwhile, Ariana is moving on with her new boyfriend, The Wanted's Nathan Sykes. She has even met his family.

Jai Brooks made some pretty serious accusations of his ex-girlfrind, Ariana Grande, when he blogged that she was unfaithful. He wrote a scathing letter against the starlet, that started off by saying, "Yes I was cheated on. Yes it does suck. Yes I was left for another man."

Ariana quickly replied to the blog, tweeting:

"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.''

Brooks latter continued his Twitter attack, adding:

"Being in Hollywood, I’ve learnt how fake people can actually be. I will never be like that, it’s pathetic. Fu** that sh**."

Now Perez Hilton is reporting that an unnamed source is denying that Ariana cheated on Jai:

"'I know the two well and this is a classic case of a nobody trying to use someone's fame as a way to leverage his own pursuit of stardom."

Meanwhile, Grande isn't letting the accusations keep her from moving on with her new boyfriend, Nathan Sykes. The two recently announced that they were dating via Twitter, with Nathan writing:

“So I guess it’s obvious now.Thanks to everyone who is being so lovely. I’m so happy #butweareterrified #pleasedontkillme #orariana.”
Sykes considers himself quite lucky to be with Grande, as is evident by what he told E! News about taking her home to meet his family:

"I took her back to Gloucester yesterday to meet all my family. I was so scared, you don’t even realize. But my family think she’s amazing and they’re like ‘Nathan, how?’ and I’m like ‘I don’t know. I don’t think anyone can ever punch above their weight, but I feel very lucky, put it that way. She’s amazing, I’m so happy... She’s a really special girl, I think the world of her and I hope we’ll be together to a very long time.”

Grande was equally nerve wrecked by meeting his parents, as she told Capital in a recent interview:

"I was really nervous because obviously I really care about him and I want them to like me and think I'm good enough. They were really sweet and lovely. I love his family. But it was so nerve wracking."
