Machine Gun Kelly (MGK) and Megan Fox are officially engaged and bound together by… blood.

Yes, the two drank each other’s blood after they got engaged.

While this caught plenty of flack and attention, MGK also got some heat for his outfit choice.

MGK wore a sequined black-and-gold turtle neck sweater, black pants and black combat boots.

One person commented on the video, “Did he dress like a referee because he wanted to make it official?”

Another wrote, “Why is he wearing a bedazzled referee shirt?”

This person hysterically replied, “Did he just come from his Foot Locker shift?”

Another comical fan wondered if MGK was wanting to look like ‘Beetlejuice.’

The couple got engaged on January 11 in Puerto Rico.
