Los Angeles, California - On the most romantic day of the year, Machine Gun Kelly has revealed a "bloody valentine's" tribute to his much-loved girlfriend Megan Fox, thereby possibly outdoing any other celebrity couple in Hollywood.

Megan and the rapper met on the set of Midnight in the Switchgrass in March 2020 and have been inseparable ever since she starred in his Bloody Valentine music video in the summer, when they also went Instagram official.

On Valentine's Day, the happy pair dedicated emotional Instagram posts to each other, including never-seen-before footage of the two.

"There goes my heart manifest outside of my body draped in the towering silhouette of a most unusually handsome boy," Megan, 34, wrote.

"I wear your blood around ," the singer wrote in tribute to his girlfriend, alongside a photo of a necklace that appeared to have a blood drop on it. "My bloody valentine," he called Megan.

The two have a very intense relationship – Megan Fox has described them as "twin flames," as in two halves of a soul.

The pair also recently sparked engagement rumors after Megan was spotted with a ring on her left hand. However, a closer look revealed the ring reads "f*** you."

According to People Magazine, the two were not engaged but were very happy with each other.

"There will be an engagement at some point, but they are not engaged now," a source told the magazine.

Megan is also still in the midst of finalizing her divorce from Brian Austin Green, with whom she shares three children.
