Megan Fox and singer Machine Gun Kelly have reportedly separated just weeks after announcing they are expecting a child together.

TMZ revealed that the couple, who are expecting their first child together, decided to part ways over the Thanksgiving holiday while in Vail, Colorado. Sources say Fox, 38, found something on Kelly's phone that upset her, leading her to leave the trip early. Kelly, 34, apparently left soon after and hasn't communicated with the actress since then.

This split reportedly occurred just two weeks after the "Transformers" actress shared that she is expecting her fourth child and her first with Kelly.

On November 11, Fox posted a series of Instagram photos where she held her baby bump while covered in oil, alongside a picture of a positive pregnancy test.

"nothing is ever really lost. welcome back 👼🏼❤," she wrote, tagging Kelly.

TMZ later stated that Fox was four to five months pregnant at the time of her announcement, with a due date in March 2025. The former couple is aware of their baby’s gender but has decided to keep it a secret for now. She is already a mother to three children with ex-husband Brian Austin Green: Noah, 11, Bodhi, 9, and Journey, 7. Meanwhile, Kelly became a father to daughter Casie, now 15, in 2009 with then-girlfriend Emma Cannon.

The rapper, whose real name is Colson Baker, addressed the pregnancy news on social media, writing on X, "isolating myself in the desert next week to restart this album from scratch." He added, "when inspiration flows through me unblocked, we will reach the destination in no time. don’t worry. after all, im [sic] about to be a dad again!"

Megan Fox and Machine Gun Kelly first crossed paths in 2020 while working on "Midnight in the Switchgrass" and got engaged two years later.

However, their celebration took a turn when the "Transformers" actress experienced a pregnancy loss. Kelly mentioned it during a performance at the Billboard Music Awards, dedicating his set to their unborn child. Fox later confirmed the loss in her poetry book, Pretty Boys Are Poisonous, released in November 2023.

“It was very difficult for both of us,” Fox said on Good Morning America in November 2023. “It sent us on a very wild journey together and separately and together and apart … trying to navigate, ‘What does this mean?’ and ‘Why did this happen?’”

Fox and Kelly's relationship has faced challenges over the years. After the pregnancy loss, rumors suggested they had parted ways.

In March, the actress confirmed they had ended their engagement, but she remarked, "There will always be a tether to him no matter what. I can’t say what the capacity will be, but I will always be connected to him somehow."
