Machine Gun Kelly may or may not have some rockstar remorse.

The “Bloody Valentine” star actually became a bloodied valentine, because he was dressed in pink from head to toe.

During an afterparty after his sold-out show at Madison Square Garden, MGK smashed a glass over his head.

“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 with a bloodied face.

Following his run-in with a champagne glass, MGK stopped by “Late Night with Seth Meyers.”

Seth asked MGK, “So, what happened last night?”

“Um you know, you know when you clink a champagne glass with a fork to kind of get people’s attention? Yeah, I didn’t have a fork,” he explained. “So, I just clinked it… on my head.”

Yeah MGK, but you had a microphone in your hand… I believe that may have fared you much better than shards of glass rocketing into your head.
