Megan Fox reacts to rumors Machine Gun Kelly cheated with ...

Megan Fox responded to rumors her fiancé, Machine Gun Kelly, cheated on her with guitarist Sophie Lloyd amid split speculation.

After the actress made headlines for a cryptic social media upload Sunday, one of her followers wondered in the comments whether the rocker “got with Sophie,” seemingly referring to the musician in his band.

Fox, 36, did not confirm nor deny the theory about Lloyd, writing, “Maybe I got with Sophie.”

The “Transformers” star added a flame emoji.

In the Instagram slideshow, Fox posed in a bathroom with a mystery man. She also burned a letter in a bonfire.

The post’s caption included lyrics from “Pray You Catch Me” from Beyoncé’s “Lemonade,” an album best known for describing her husband Jay-Z’s infidelity.

“You can taste the dishonesty / it’s all over your breath,” the “Jennifer’s Body” star wrote.

The “New Girl” alum went on to unfollow MGK, whose real name is Colson Baker, only following three A-listers — Eminem, Harry Styles and Timothée Chalamet — before deleting her account altogether.

MGK, who has had a long-standing feud with Eminem, has yet to address breakup rumors. Page Six has reached out to his and Fox’s reps for comment.

The songwriter did, however, perform at a Super Bowl party Saturday night, dedicating his hit “Bloody Valentine” to “the ladies.”

A rep for the party confirmed to Page Six that Fox was not on site while the Grammy nominee took the stage. She also did not accompany the actor on the red carpet.

The “Midnight in the Switchgrass” co-stars have been together since 2020, getting engaged two years later.

When the duo attended events surrounding the Grammy Awards last week, Fox sported a hot pink cast after breaking her wrist and suffering a concussion.
