Machine Gun Kelly is living his best belated “Bloody Valentine” life.

The rockstar sold out Madison Square Garden (MSG) on Tuesday, June 28, with his Mainstream Sellout Tour.

This is an amazing feat and career high for any performer. MSG can hold nearly 21,000 people, 20,789 to be exact.

MGK was on an absolute high last night and continued the party at Catch Steakhouse in New York City.

He uploaded videos from the evening’s festivities to his Instagram Story early Wednesday morning.

MGK was seen performing and speaking to the crowd before he did the unthinkable…

“I don’t give a f**k, bro, I don’t give a s**t,” he said before breaking a champagne flute over his head.

Partygoers gasped in horror, before MGK continued his performance of “My Ex’s Best Friend” with a bloodied face.

He captioned the video, “and this is when things turned…🤣.”
