Megan Fox's engagement ring, which was designed by fiancé Machine Gun Kelly, has a painful aspect to it.

The diamond and emerald ring's bands are actually thorns, Machine Gun Kelly, whose real name is Colson Baker, told Vogue magazine.

Machine Gun Kelly worked with Stephen Webster to create the ring and opened up about the concept in the recent interview.

"It’s a thoroughbred Colombian emerald, with no treatment," Machine Gun Kelly explained. "It was just carved into the teardrop, straight out of the mine. And the diamond was directly from Stephen."

"The concept is that the ring can come apart to make two rings," he continued. "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. And you see this right here? The bands are actually thorns. So if she tries to take it off, it hurts…"

"Love is pain!" Machine Gun Kelly then quipped.

Machine Gun Kelly proposed to Fox on Jan. 11. The two later announced their engagement on social media. The musician videoed the proposal on his phone and explained the couple released it on social media to "control the narrative."

"We released it to control the narrative. As opposed to someone just catching a weird cell phone picture of a ring on our hand and being like, ‘Whoa!’" he told Vogue.

"I just recorded it on my cell phone. And it wasn’t like we had photographers or anything. It was just like me setting my phone against a cup."
