It seems a catfight is about to ensue in court as Perez Hilton claims that Ariana Grande is doing cocaine. In an article on Celebrity Dirty Laundry, the gossip blogger says that someone saw the singer using the illegal substance during a recent party.

Hilton tweeted, "@ArianaGrande Are you okay? I heard someone saw you doing cocaine at a party this weekend. Stay away from drugs, Arianna!!!" This was followed by "@ArianaGrade I'm praying for you! You can overcome this! #JustSayNoToDrugs"

It's both sad and funny how the gossiper tries to use the sympathetic approach in spreading rumors about Ariana's drug use.  But Hilton went even further and got the singer's mother, Joan Grande, and half brother Frankie involved in the issue.  

He tweeted, "@joangrande I am sending positive thoughts your way! Hopefully @ArianaGrande can overcome these drug problems/rumors," and "@FrankieJGrande Please make sure @ArianaGrande stays away from cocaine. I'm hearing awful things about what she's been doing."

People close to Ariana are speculating that Hilton spread the rumors to take revenge on her. According to Celebrity Buzz, an insider close to Ariana said that Hilton once approached the singer and offered to be her manager but got rejected.

Plus, following Hilton's not-so-flattering comments on the singer's look during the Grammy's, Arianna's fans have been defending their idol by attacking the blogger through his various online accounts.

Hilton retaliated by posting Arianna's picture on Instagram and ranted, "I know most @ArianGrande fans are 12 years old - at least they almost act like it - but enough is enough! Even 12 year olds know better than to wish death on a baby and say disgusting things that 99% of her fans have been spamming my Instagram with."

According to Ariana's camp, the Nickelodeon star is planning to sue Hilton for spreading the rumors and is already "hiring litigators to sue him for slander", The Hollywood Gossip reports.
