The controversial business magnate divided fans after becoming the latest high profile figure to take the reins of the long-running show on May 8th.
But the mixed opinion was put to one side as Musk, 49, partied in to the early hours with Grimes – real name Claire Boucher – and SNL co-star Miley in New York City.

Sporting a garish striped sweater with fringed sleeves and an oversized, off-the-shoulder silhouette, Miley, 28, ensured she caught the eye while making her way into Ian Schrager’s PUBLIC hotel in the Lower East Side.
The singer added to her look with a pair of cropped trousers, while stylish black leather boots and a matching handbag rounded things off.
In accordance with current health and safety guidelines she shielded her face behind a protective mask as she made her way across the sidewalk with a bodyguard.

The decision to tap the Tesla CEO and ‘Technoking’ Elon Musk to host the NBC sketch comedy show was seen as a risky gambit by creator Lorne Michaels to boost ratings and expand audience.
For the first time in SNL’s 46-year history, the episode featuring Musk aired live internationally on YouTube in more than 100 countries. The stream was not available to U.S. viewers.
‘SNL is a global phenomenon and this livestream marks the first time audiences around the world will experience the show simultaneously along with the US,’ Frances Berwick, chairman of NBCU’s entertainment networks, said in a statement.

‘It’s incredibly exciting to create this worldwide event with host Elon Musk and musical guest Miley Cyrus,’ he added.
Saturday’s episode of the show quickly became one of the most hotly-anticipated of all time, due to the decision to cast the controversial Tesla boss as host for the evening.
The decision drew an instant backlash from its long-running cast members when it surfaced last month, with many making digs at Musk on social media.

Even hours before the live show, tensions were still simmering with sources saying some cast members ‘are getting a little too big for their britches.’
Musk’s girlfriend Grimes also hinted she will be joining him and Miley in an Instagram post where she told fans: ‘Tune into SNL tonight and watch me try acting’.
Grimes did appear as Princess Peach for the Mario Trial.
