Ariana Grande is going to sue Perez Hilton for cocaine claims

Ariana Grande does NOT have a cocaine problem, despite a completely FALSE rumor started by Perez Hilton.

On Sunday, the blogger began barraging the singer with faux concern on Twitter, writing, “Are you okay? I heard someone saw you doing cocaine at a party! Stay away from drugs Ariana!!!”

Perez also tweeted to Grande’s brother Frankie, “Please make sure Ariana stays away from cocaine. I’m hearing awful things about what she’s been doing!”

He even wrote to Nickelodeon, where the actress works on “Sam & Cat,” saying, “Hopefully you guys can help her before it’s too severe!”

But Perez’s claims are 100 percent untrue, and Grande is planning to sue the blogger for his false allegations.

A close Grande source tells Gossip Cop exclusively that Perez’s claims are “all lies” and “not true.”

In fact, we’re told the star is so anti-drugs that she’s even afraid to take over-the-counter medication like Tylenol.

Music insiders speculate that the cocaine allegations may be a “vendetta” by Perez, who allegedly tried to be Grande’s manager.

He “approached her and got rejected,” says one music industry bigwig, who feels his attacks against her and her fans are “personal.”

The blogger’s claims may also be retribution for some of Grande’s fans allegedly writing mean comments about the blogger’s son.

Perez even tweeted to Grande, “For every day your fans continue to spam me on social media, I will continue to tweet you. I know you see my tweets. I win! :-)”

Gossip Cop hears from an Grande confidante that she’s already “hired litigators to sue him for slander.”
