Designed her ring so that it hurts when she takes it off: Machine Gun Kelly on Megan Fox

Talking about the concept behind his fiancée Megan Fox's ring, rapper Machine Gun Kelly said, "When it’s together, it’s held in place by a magnet. So you see how it snaps together? And then it forms an obscure heart." He further said, "The bands are actually thorns. So if she tries to take it off, it hurts."
