New tensions appear to be rising between Megan Fox and actress Sydney Sweeney, amid reports that Megan’s ex-fiancé, Machine Gun Kelly (MGK), is getting close to his Johnny & Clyde co-star.
According to a recent report by RadarOnline, Fox is feeling increasingly uneasy about MGK’s growing bond with Sweeney. The source of the alleged drama? MGK—real name Colson Baker—has reportedly shown a strong interest in the Anyone But You actress.
Though MGK has denied rumors of infidelity during his relationship with Fox, insiders say his behavior around Sweeney is raising eyebrows. “He can’t help himself, and his carrying on with Sydney is proof of that,” a source claimed. “He’s always had a thing for Sydney, who is Hollywood’s ‘It’ girl.”
Sweeney, who has been gaining attention for both her acting roles and recent entrepreneurial ventures—including a new men-targeted bathwater soap line—has found herself inadvertently in the middle of this rumored love triangle. Megan Fox and MGK were previously engaged in January 2022 after a tumultuous relationship filled with ups and downs.

However, they officially split in late November 2024, just weeks after announcing they were expecting a child together. Their daughter was born in March, and the two are now said to be focusing on co-parenting, putting past issues aside for the sake of their newborn.
“She’s doing well and enjoying her newborn,” a source close to Fox shared. “Colson is around a lot, and Megan seems happier with him. She hasn’t mentioned that they are back together, though.” The situation remains delicate, particularly given the emotional toll the breakup reportedly took on Fox during her pregnancy.
“It was heartbreaking for her to be pregnant and not be able to trust her partner,” the insider added. “They are just focused on their baby girl now.” While MGK and Fox are said to be in a better place emotionally, the speculation surrounding his closeness with Sweeney threatens to disrupt the fragile peace they’ve built.
Neither Fox, MGK, nor Sweeney has commented publicly on the rumors, but with all three frequently in the spotlight, attention on their dynamic is unlikely to fade anytime soon. As it stands, the focus appears to be on co-parenting their newborn daughter, but lingering questions about trust and new connections continue to follow the former couple.
