Saturday Night Live Executive Producer Lorne Michaels is reportedly sending Pete Davidson to treatment after the comedian posted an alarming message on Instagram saying he didn't want to be 'on this earth anymore'.

A source close to the SNL creator said in a statement to Page Six: 'The decision was taken to give Pete a break on Saturday night – his sketches were dropped before the early evening rehearsals.

'Lorne has pledged to help all he can, including sending Pete to get help. Everyone on the cast is hugely protective of him and were obviously upset - particularly Colin Jost and Michael Che on 'Weekend Update.'"

It's currently unclear where the the SNL cast member will be staying for treatment. The gossip site reports that Davidson hasn't made plans to take much time off - and could return to the set shortly after the New Year.

The report comes shortly after it revealed Davidson refused to see his ex-girlfriend, Ariana Grande, after she rushed to be by his side at the SNL studio over the weekend.

On Saturday, Davidson penned the harrowing message in a since-deleted post on Instagram which terrified his friends, family and fans.

He wrote: 'I really don't want to be on this earth anymore. 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.' He concluded with a heart emoji.

Following the comment, the New York Police Department sent an officer to SNL's studios in Manhattan to ensure the star was present and not in distress, according to the New York Times.

Separately, an NBC staffer called the NYPD to confirm that Davidson was in fact in the building and 'fine.'

Davidson made a brief appearance in the live taping of SNL to introduce musical guest Miley Cyrus.

Davidson has a history of mental health problems that he has been very open about. And, rapper MGK has been open about his past addiction to heroin.

The actor told Teen Vogue in August, 'I've been in and out of mental health facilities since I was nine,' adding he had made a suicide attempt in the past.

His father, a New York City firefighter, died during the terrorist attacks on 9/11.

Grande also showed up at SNL studios to check on Pete, who she recently broke up with ; seen in August

Grande, his former fiance, was very concerned about Pete and said she was 'sorry'

When he was in high school he was diagnosed with Crohn's disease and started smoking marijuana to relieve some of his symptoms.

The star went to rehab twice where it was discovered he had bipolar disorder.

'The last few years have been real rough with me. I took all these mental health classes and really spent a lot of time getting me good,' he told the magazine.

After his note was shared on Saturday, Ariana Grande, his former fiance, showed up at his SNL office where he was rehearsing to make sure he was fine.

The No Tears Left To Cry singer tweeted, 'I'm downstairs and I'm not going anywhere if you need anyone or anything.

'I know u have everyone u need and that's not me, but i'm here too. I really didn't mean any harm. all i want everyone to be healthy and happy. so desperately. please. my god.'
