Machine Gun Kelly and Megan Fox are the celebrity couple that broke the internet — with a little blood along the way.
"Achingly Beautiful Boy... My heart is yours," Fox, 36, wrote alongside a selfie of her with Kelly (real name: Colson Baker, 32) in the summer of 2020 when they debuted their relationship.
It seems the two go viral every time they make a public appearance, give a joint interview, or post a gushing Instagram caption about drinking each other's blood.
"People are imagining us with goblets and we’re like Game of Thrones, drinking each other’s blood,” Fox told Glamour in a cover story published April 26. “It’s just a few drops."
Here's a guide on everything you need to know about the newly-engaged couple's relationship, from Fox splitting from husband Brian Austin Green, to Kelly's sentimental proposal with a thorn ring.
April 26, 2022: Megan Fox confirms blood drinking, says she manifested MGK
Some couples share milkshakes — Fox and MGK share each other's DNA.
In an interview with Glamour UK, published April 26, Fox confirmed that the blood drinking she mentioned in her Instagram caption to announce she and MGK were engaged was not just a figure of speech.
"Yes, we do consume each other’s blood on occasion for ritual purposes only," Fox said. "When I do it, it’s a passage or it is used for a reason. And it is controlled where it’s like, ‘Let’s shed a few drops of blood and each drink it.’ (MGK is) much more haphazard and hectic and chaotic, where he’s willing to just cut his chest open with broken glass and be like, ‘Take my soul.’ ”
Fox and MGK often describe each other as their "twin flame." The "Transformers" actress also added that she believes she manifested her relationship with MGK as a young child.
"He’s literally my exact physical type that I’ve been manifesting since I was 4. I’m also four years older than him," Fox said about her fiancée. "So, I think I made him."

Leave it to Fox and Kelly to announce their engagement with the most intense Instagram captions to celebrate.
The couple revealed Jan. 12 Kelly had proposed the day prior, after roughly a year and a half of dating. Fox wrote that in July 2020, the same month the couple first went public with their relationship, the two sat under a banyan tree and "asked for magic."
"We were oblivious to the pain we would face together in such a short, frenetic period of time," Fox wrote. "Unaware of the work and sacrifices the relationship would require from us but intoxicated off of the love. And the karma."
They returned to that spot for a special moment. In a video posted by Fox, the two are seen kneeling down in front of one another atop a flight of stairs outside. Fox is wearing a sultry black cutout dress with Kelly donning a sparkling white and black top.
"Somehow a year and a half later, having walked through hell together, and having laughed more than I ever imagined possible, he asked me to marry him," she continued. "And just as in every lifetime before this one, and as in every lifetime that will follow it, I said yes."
And then, Fox wrote, "we drank each other's blood."
Posting on his own Instagram account, Kelly shared a close-up of the stunning ring, two pear-shaped stones – one emerald, one diamond – together on one band. The rapper elaborated on the design, saying that "the emerald (her birth stone) and the diamond (my birth stone) set on two magnetic bands of thorns that draw together as two halves of the same soul forming the obscure heart that is our love," he wrote.
In a Q&A with Vogue published Jan. 17, Kelly elaborated on the meaning behind the engagement ring he gave Fox, adding that the bands of the rings "are actually thorns."
"So if she tries to take it off, it hurts," he added. "Love is pain!"

Kelly added that their relationship "should be light, but also we go to hell with each other."
"It’s ecstasy and agony for sure," he said. "I don’t want people to think anything’s perfect with us. I didn’t say it was the darkest fairy tale for no reason."

“I will always love her,” Green added on his podcast. “And I know she will always love me and I know as far as a family, what we have built is really cool and really special.” He said the former couple will “still do family vacations and holidays as a family and really make that a focus for the kids.”
