We don't know the name of their daughter, but their "celestial seed" is MGK's second child/daughter, as he also a 15-year-old with ex Emma Cannon named Casie. Fox's daughter is her first, as she has three sons with ex Brian Austin Green, 12-year-old Noah Shannon, 11-year-old Bodhi Ransom and nine-year-old Journey Heart.

The on-again, off-again couple broke up in November 2024, weeks after the “Transformers” star debuted her baby bump.

Megan Fox and Machine Gun Kelly have welcomed their baby girl to the world. Machine Gun Kelly shared the news in a sweet Instagram post on Thursday, which included a black-and-white video of his daughter's small hands. "she’s finally here!! our little celestial seed 🥹💓♈️♓️♊️," he captioned the post, along with the date of her birth.
