Machine Gun Kelly fires back at Sydney Sweeney dating rumours with a ‘shut up’ that shoots up fan speculation

If 2025 has given us anything, it is unhinged celebrity drama, and MGK x Sydney Sweeney is the latest ship to cause chaos online. The two have been spotted together a little too often lately, especially since their respective breakups, and fans have questions.

The rumours, the photos, and the Vegas mood of Sydney Sweeney and MGK

In May, the pair were seen embracing at a flashy Vegas club launch, and soon after, MGK dropped an Instagram carousel with a snap of him and Sweeney flashing peace signs like it was 2012 Tumblr energy all over again. Oh, and Sydney? She posted a Story that featured MGK and Patrick Schwarzenegger too. Coincidence? We think not.

MGK on WWHL says 'shut up'

Fast forward to Sunday, August 10th, Machine Gun Kelly (aka Colson Baker) landed in the hot seat on Watch What Happens Live with Andy Cohen. A fan named Kyle P asked the question on all of our minds: “Is there any truth to the rumour that you and Sydney Sweeney are more than just friends?”

MGK, clearly over it, shook his head, stared down the camera like it owed him money, and told Kyle to “shut up.” Laughter exploded in the studio, but the internet? Not laughing they are investigating.

Sources say MGK’s response was dripping in deflection. “He laughed it off, but didn’t exactly deny the closeness,” one fan posted. Another noted: “The way he avoided the question? Classic situationship energy.”

Just friends or star-crossed lovers?

For context, MGK and Sydney go way back. She starred in his 2021 directorial debut Downfalls High and appeared alongside him and Pete Davidson in Big Time Adolescence back in 2019. So yes, they have history, but is it friendly or flirty? Both are now single. MGK officially split from Megan Fox in December 2024 and recently welcomed baby Saga (yes, that is the name) with her.

Meanwhile, Sweeney’s engagement to Jonathan Davino is officially over as of May. The stars have aligned, literally.

Alien dads, frank sinatra, and more chaos

As if that was not enough weirdness, MGK veered into sci-fi territory during the same interview. When asked about age, he said he was unsure if it “exists” and hinted at possibly having alien origins. Allegedly, he once asked his mum if she had ever disappeared mysteriously, and she admitted to an abduction. Yup, that happened.

Also, his dream musical collab? Frank Sinatra. MGK said he “likes Frank” and would love to collab. Time traveller confirmed?
