Machine Gun Kelly is his own bloody Valentine with his latest razor-sharp tattoo.

The rapper, who turned 31 on Thursday (April 22), not only viciously sliced through a candy-filled birthday cake Wednesday night, but he also got some new ink that looks like someone sliced his neck. He showed off photos and a video of himself getting a gruesome vertical line tattooed in red ink down his neck, right above his tattoo of the title of his Billboard 200 No. 1 album Tickets to My Downfall.

“If anyone ever liked my neck,… it’s going to look different,” MGK deadpanned, writing “Bye bye neck” in his Instagram caption on Tuesday. Einer Banz, who co-wrote and -produced Polo G’s current Billboard Hot 100 No. 1 hit “Rapstar,” was easily deceived and “thought that was a legit slice in ur neck,” he commented. The rapper’s “Burning Memories” collaborator Lil Skies mused, “Wow love it!”

The “Bloody Valentine” singer also announced he “yatted the neck” on Twitter.
