Los Angeles, California – Many fans are speculating that the engagement of Travis Barker and Kourtney Kardashian might inspire Machine Gun Kelly to pop the question to his leading lady, Megan Fox.

It's been a whirlwind of a year of love for both couples, who just happen to be best friends.

But now that Barker has officially made Kardashian his future wife, speculation around whether Machine Gun Kelly will follow in his question-popping footsteps has skyrocketed.

On Tuesday, Deux Moi, a publication that runs celebrity rumor stories, shared a tip submission to their since-deleted Instagram Story that commented on the potential for an upcoming proposal.

The tip itself wasn't about Fox or Machine Gun Kelly, born Colson Baker, but Deux Moi added on-screen text to the screenshot that read, "Also new celeb besties are doing back to back engagements, announcing soon."

This comment sent the rumor mills ablaze, with fans carrying out the speculation on other social media platforms.

On Tuesday afternoon, NPR and Rolling Stone writer Ilana Kaplan tweeted her two cents on the matter, "I feel like an MGK and Megan Fox engagement is imminent."

On Wednesday evening, Twitter user Molly DiLalla said, "MGK and Megan Fox are going to announce their engagement soon, and they’ll [probably] have a joint wedding that’s punk rock-themed with Travis and Kourtney."

At this point, the only people who have remained tight-lipped about a possible proposal in the wake of Kravis' are Fox and Machine Gun Kelly themselves.

But if there's one thing the rapper turned rock star loves more than Fox, it's the element of surprise.

Could Machine Gun Kelly be secretly planning a proposal?
