Ariana Grande has found herself in a difficult spot.

On Monday blogger Perez Hilton tweeted he’s worried about the 20-year-old performer because he heard she was doing cocaine at a party.

But the 35-year-old father didn’t stop there. He also reached out to her brother and the network that airs her show Sam & Cat to voice his concerns. Now the Yours Truly singer has hired lawyers to sue Hilton for slander, according to Gossip Cop

Ariana’s reps did not return calls to MailOnline.

An ugly battle on Twitter: Ariana Grande (left in November) has been accused by blogger Perez Hilton (right) of doing cocaine

These are fighting words: On Monday the 35-year-old blogger tweeted not just the 20-year-old performer but also her brother and the network for her Sam & Cat TV series

But this outfit is so cute!: The beauty’s fans slammed Hilton when he wrote Grande was dressed ‘awfully’ at the Grammys, starting a war

A source told Gossip Cop on Thursday the drug claims are ‘all lies’ and that she has already ‘hired litigators to sue him for slander.’

It all started when the blogger – who launched his career by slamming celebrities – reached out to the singer on Twitter, writing, ‘Are you okay? I heard someone saw you doing cocaine at a party! Stay away from drugs Ariana!!!’

He then wrote, ‘I’m praying for you! You can overcome this!’ He added the hashtag JustSayNoToDrugs.

Perez also tweeted to Grande’s brother, ‘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 the series Sam & Cat, saying, ‘Hopefully you guys can help her before it’s too severe!’

A day later he tweeted this threat to the young beauty: ‘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! :-)’

That same day he wrote a long note explaining his actions: ‘I know most @ArianaGrande fans are 12 years old… but ENOUGH is enough.’

He went on to argue that her fans are wishing death on his son because he said she was dressed ‘awfully’ at the Grammy Awards which took place on January 26.

The Nickelodeon darling wore a floral print strapless dress with pink pumps.

Hilton added he thinks her silence is making it seem like she condones her Twitter followers’ hateful messages.

Toward the end of his note he wrote: ‘Quite (sic) being such an enabler and SAY SOMETHING! Until then, I guess I will be a baby myself and do what I think I need to do to get this bulls*** to stop. All this silliness started over me saying I did not like her look!’

A threatening message: The outspoken blogger admitted he would continue ‘to do what I think I need to do to get this bulls*** to stop’

Her fans have been so outraged by Perez’s drug comments that the star had to address their anger on Thursday through Twitter by writing, ‘arianators, I know u don’t like when ppl say bad things about me but please don’t wish negativity upon any1. don’t give up ur light, I ❤️ u.’

Gossip Cop’s insiders have said the cocaine allegations may be a ‘vendetta’ by Perez, who allegedly tried to be Grande’s manager.

He ‘approached her and got rejected,’ a close family confidant told the site.

Grande is managed by Scooter Braun, who also works with Justin Bieber.

The source added that the ‘attacks against her and her fans are “personal.”‘

It is also believed the drug claims may be ‘retribution’ after Grande’s fans allegedly wrote unkind things about Perez’s son.

But she has spoken up: On Thursday the Put Your Hearts Up singer asked her followers to not ‘wish negativity upon any1’
