Machine Gun Kelly Designed Megan Fox’s Engagement Ring to Represent Their Unique Relationship

Megan Fox is “very upset” with Machine Gun Kelly after a fight over the weekend, a source tells PEOPLE.

A source says the actress, 36, is not on speaking terms at the moment with her musician fiancé, 32, following a dispute during Super Bowl weekend. “Megan is very upset. They had a fight over the weekend and Megan won’t speak to him,” says the source.

“They haven’t officially called off the engagement, but Megan took her ring off,” the source adds, noting that while the couple “have had issues in the past, things seem pretty serious this time.”

Reps for Fox and Kelly have not responded to PEOPLE’s requests for comment.

Fox first hinted at a possible breakup between them on Instagram Sunday when she uploaded a post and captioned it with lyrics from Beyoncé’s 2016 album Lemonade.

“You can taste the dishonesty/ it’s all over your breath,” Fox wrote alongside her post, which included photos of herself and a video of an envelope being burned in a fire. The actress also wiped all photos and videos of herself and Kelly from her Instagram page then deleted her Instagram account entirely hours later.

In the comments section of Fox’s last post before she deleted her account, one fan suggested that Kelly was unfaithful in the couple’s relationship, writing, “He probably got with Sophie.” Fox jokingly responded that it could’ve been her: “Maybe I got with Sophie.”

Fox was absent from the Sports Illustrated Super Bowl Party on Saturday night, where Kelly performed, a source told PEOPLE. However, the pair attended Drake’s party together the night before on Friday.

Before Fox deleted her Instagram account, she also followed Eminem, who has publicly feuded with Kelly for years. Kelly’s Instagram profile still features multiple photos of him with Fox.

The pair met on the set of the indie thriller Midnight in the Switchgrass in March 2020, and though production was quickly halted due to the pandemic, Fox and Kelly, whose real name is Colson Baker, were spotted spending quality time together shortly after.

Fox recently joined Kelly for the 2023 Grammys, where he was nominated for best rock album, and praised him for handling his loss at the awards show with “a grace and maturity that I haven’t seen from you before” in a now-deleted tribute shared to Instagram.
