Megan Fox embraced a dark, mythological aesthetic for the Halloween season, transforming into a gothic mermaid in a series of striking photographs shared to her Instagram account on Saturday. The 40-year-old actress captivated her followers by channeling a deadly siren, complete with a haunting caption that read, "the song was the trap, and the sea was the grave."
The visual presentation featured Fox plunging into dark, moonlit waters while dressed in a shimmering silver bra paired with a sheer grey mermaid tail. Her look was elevated by intricate details, including eerie webbed fingers tipped with dramatically long, shimmering dark nails. Her face was adorned with glittering gems and completed with iridescent silver and violet glam, reinforcing her gothic transformation.
This captivating social media display arrives closely on the heels of public interest surrounding her former fiancé, Machine Gun Kelly, and his developing relationship with actress Dakota Johnson. However, sources close to Fox indicate that she remains entirely unbothered by her ex-partner’s new romance and has no intentions of involving herself in his personal life.
Fox, who shares 18-month-old daughter Saga Blade Fox-Baker with the 36-year-old musician—whose real name is Colson Baker—is reportedly single and intends to remain so while concentrating on her career endeavors and her role as a hands-on mother. According to insiders who spoke with TMZ, her primary focus is on building her business ventures and caring for her children. This professional drive follows her recent launch of an exclusive content page on Subs.com and a promotional advertising campaign for the telehealth company Ro.
The former couple officially called off their engagement in November 2024, a split that reportedly occurred just four months before they welcomed their daughter in March 2025. Their separation followed claims that the actress discovered the musician had been communicating with other women. Today, sources confirm that Fox and Machine Gun Kelly maintain no romantic connection outside of co-parenting logistics concerning their young daughter.
"MGK and Megan are done and only communicate about their daughter and co-parenting logistics," a source revealed to Us Weekly in late September. "They both know they have toxic tendencies and it’s much better this way." The insider added that while the rapper "will always love Megan and have a soft spot for her," he ultimately "gave up pursuing a romantic relationship with her several months ago."
Prior to the birth of their daughter, Fox and Machine Gun Kelly navigated a turbulent, on-and-off relationship that spanned approximately four and a half years. In addition to their toddler, Fox is mother to three sons—Noah, 14, Bodhi, 12, and Journey, 10—whom she shares with her former husband, Brian Austin Green. Meanwhile, Machine Gun Kelly is father to 17-year-old daughter Casie, whom he shares with his ex, Emma Cannon.
Despite the rocky conclusion to their romance, a source noted to People earlier this year that their dynamic transitioned into a cooperative space centred on their child. "Their relationship at this point is just about co-parenting. Megan is focused on her kids and the baby and just getting settled into this new chapter. That’s genuinely her priority," the source stated at the time, adding that Fox was appreciative of how the musician stepped up to support both her and the baby during the transition into early parenthood.
While Fox focuses on her family and entrepreneurial ventures, Machine Gun Kelly has been linked to Dakota Johnson, 37. Speculation surrounding the new pairing intensified after Johnson was spotted waiting for the musician outside a Los Angeles recording studio. Insiders recently indicated that the connection between Johnson and Machine Gun Kelly began to heat up following time spent together at the July 4 wedding of Taylor Swift and Travis Kelce.
A source told the Daily Mail that Johnson has described her chemistry with the rapper as exceptional, pointing to a strong foundation built on an initial friendship that allowed them to know each other well before entering a romantic dynamic. Additional sources close to Johnson have suggested that the couple shares similar long-term aspirations regarding family, having discussed their future prospects following Johnson’s high-profile six-year relationship with Coldplay frontman Chris Martin, as well as past connections with musicians Role Model and Matthew Hitt.
