Megan Fox Was "Surprised" When Machine Gun Kelly Proposed on Puerto Rico Vacation: Source Green confirmed his split from Fox after nearly 10 years of marriage in May 2020. She and Kelly, 31, began dating that month, after meeting on the set of the Randall Emmett-directed film Midnight in the Switchgrass. In a video posted Wednesday, the "Bloody Valentine" musician got down on one knee and popped the question to Fox, who happily accepted. She said the pair also sealed the union by drinking each other's blood. "The proposal was a surprise," the Fox source tells PEOPLE. "They have traveled to Puerto Rico before, so Megan just assumed it was another vacation." According to the insider, the Jennifer's Body actress "loved the proposal" and "thought it was beautiful and perfect." RELATED VIDEO: Machine Gun Kelly Designed Megan Fox's Engagement Ring to Represent Their Unique Relationship "She is excited to get married," adds the source. Alongside his engagement announcement, Kelly shared an up-close video of the gorgeous emerald and diamond engagement ring he had custom-made by Stephen Webster for the occasion. In the video, the pear-cut stones shimmer as the Transformers actress moves her hand. In the caption of his post, the Born with Horns artist explained the design choice. "I know tradition is one ring, but I designed it with Stephen Webster to be two: 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.
