Ariana Grande denied entry to see Pete Davidson following worrying message - report

Warning: This article discusses mental health issues and suicide.

Comedian Pete Davidson reportedly told his security team to keep ex-fiancée Ariana Grande at bay when she rushed to see him after he posted a worrying note online. 

The troubled Saturday Night Live star, who recently opened up about feeling suicidal as a result of cyber-bullying, alarmed fans and friends with a now-deleted Instagram post that appeared to reference suicide.

"I really don't want to be on this earth anymore," he wrote.

"I'm doing my best to stay here for you but I actually don't know how much longer I can last. All I've ever tried to do was help people. Just remember I told you so."

Many celebrity friends of Davidson leapt into action - former co-star Jon Cryer took to Twitter to try and locate the 25-year-old, and close friend and rapper Machine Gun Kelly immediately got on a plane to go and see him.

Davidson was located at the Saturday Night Live studios, where TMZ reports Grande was told she would not be able to see her ex.

The gossip website claims mutual friends of the pair alerted Davidson to the 'Thank U, Next' hitmaker's arrival ahead of time, so he instructed his security team to keep her away.

In a since-deleted tweet, Grande appeared to reach out to her ex-fiancé publicly.

"I'm downstairs and I'm not going anywhere if you need anyone or anything," she wrote.

"I know u have everyone u need and that's not me, but I'm here too."

Earlier this month, Davidson addressed how the fallout from his high-profile relationship with Grande had affected his mental health.

"I'm trying to understand how when something happens to a guy, the whole entire world just trashes him without any facts or frame of reference," he said.

"I just want you guys to know. No matter how hard the internet or anyone tries to make me kill myself. I won't," he wrote at the time.

Grande and Davidson split in October. They had become engaged shortly after they made their relationship public in May.
