Pete Davidson Looks Happy at Knicks Game After Addressing Bullying

Pete Davidson gets by with a little help from his friends ... and courtside seats at the Knicks game.

The 'SNL' star looked like he was really enjoying himself Monday night at Madison Square Garden, as he watched his NY Knicks take on the visiting Washington Wizards. Pete was smiling and having a drink while seated next to his pals -- comedian John Mulaney and actress Chloe Sevigny.

Not sure who the guy in the Washington shirt is, but he should be happier now ... his team won.

Pete's good time came hours after he addressed online the public bullying he's been dealing with since his relationship with Ariana Grande began ... and after it ended. Pete blasted the trolls for harassing him, saying ... "No matter how hard the internet or anyone tries to make me kill myself. I won't."

Grande responded online early this morning, telling her fans to "be gentler" with Pete and others ... saying she cares deeply about Davidson and his health. She added ... "I will always have irrevocable love for him and if you've gotten any other impression from my recent work, you might have missed the point."
