Machine Gun Kelly appeared to reveal he wears Megan Fox's blood in a necklace in his most recent Instagram post.

For Valentine's Day, Kelly shared a photo dump of pictures of himself and Fox to his Instagram.

Most of the pictures in the post are of the couple posing together, but the second photo in the set is of a necklace Kelly wears.

The necklace has an orb full on a chain. It appears to be filled with clear liquid with a drop of red in the center.

He captioned the post, "I wear your blood around my neck," seeming to indicate that the necklace contains Fox's blood.

Representatives for Kelly didn't immediately respond to Insider's request for comment regarding the necklace.

Although the practice is far from mainstream, Kelly wouldn't be the first celebrity to wear his partner's blood around their neck if the necklace does in fact contain Fox's blood.

Billy Bob Thornton and Angelina Jolie famously wore each other's blood in necklaces during their relationship in the early 2000s.

Fox and Kelly have been together since mid-2020 after meeting on the set of "Midnight in the Switchgrass" in March of last year.

They've been inseparable ever since, frequently showing off their love for each other on social media and attending awards shows together.

Fox, who calls Kelly her "twin flame," also shared new photos of herself and Kelly on Instagram for Valentine's Day, though the post made no mention of her or Kelly's blood.

Her caption on the post read like a poem about her love for Kelly.

"There goes my heart / manifest outside of my body / draped in the towering silhouette of a most unusually handsome boy," Fox wrote.

"Magical and haunted / kinetic and tortured / ethereal and dangerous / cosmic / lawless / eternal / creative genius," she also wrote. "The journey will likely be perilous / but there is no destination without him."

Fox previously described her and Kelly's relationship as "intense" in an interview with Nylon.

"Loving him is like being in love with a tsunami or a forest fire," Fox told Naomi Fry for Nylon. "The intensity of merging with him is just overwhelming, and the threat it poses is so powerful but so beautiful that you have no choice to surrender with reverence and with gratitude."

Fans also believe Fox got a tattoo on her collarbone in honor of Kelly, highlighting their connection.
