Were Machine Gun Kelly and Sydney Sweeney ever an item?

That seemed to be the question on everyone's minds after the Tickets to My Downfall hitmaker, born Colson Baker, posted a photo with the actress earlier this year.

Sweeney posed alongside MGK, Patrick Schwarzenegger, and celebrity hairstylist Glen Oropeza in May, following the grand opening of the Palm Tree Beach Club in Las Vegas earlier that month, which Sweeney highlighted on her Instagram Story.

Page Six released video footage from the event where Kelly and Sweeney were seen hugging, prompting fans to wonder if there might be a romantic spark between them.

The "Rap Devil" hitmaker shut down speculation during the August 10 episode of Watch What Happens Live With Andy Cohen, where a fan asked if he and the Anyone But You actress "were more than just friends," per US Weekly.

"Shut up, dude," MGK responded.

The standout recently took a trip to Costa Rica with his former partner, Megan Fox, with whom he shares a four-month-old daughter, Saga Blade. Just last week, an insider told US Weekly that the exes are potentially trying to rekindle their romance.

"Things feel back to ‘normal’ between them, but they are not putting a label on their relationship. They’re still being intimate and technically trying to work things out to reconcile. This trip is a big stepping stone in that direction."

Sweeney called off her engagement with her ex-fiancée, Johnathon Davino, in March due to conflicting schedules.
