Machine Gun Kelly and Megan Fox have not revealed their newborn daughter’s name — their fans, however, have made a wild guess.

MGK, 34, took to his Instagram Stories on Monday, March 31, to comment on a false report that he and Fox, 38, had named their baby “Celestial Seed.”

“Wait guys … her name isn’t ‘Celestial Seed,’” MGK, whose real name is Colson Baker, captioned his post, adding a crying laughing emoji. 

He explained that Fox “is gonna tell you the name when we’re ready.”

The rapper and the actress announced the baby’s arrival on Thursday, March 27. They’re “so happy to be parents together,” a source exclusively told Us Weekly following the birth. The insider added that despite their split, MGK has been around to “support and take care” of Fox.

“No matter how they’ve felt about each other, they have always wanted to have a child together,” the source said. “They have both been communicating and are in a good place.”

According to the insider, Fox was excited about the baby’s star and moon signs, and saw “great potential” after reviewing her birth chart.

“She’s finally here!! our little celestial seed 🥹💓♈️♓️♊️ . 3/27/25,” MGK gushed via Instagram, announcing the newborn’s arrival alongside a video of her.

Fox and MGK revealed the news hours after Fox’s ex-husband, Brian Austin Green, took to his Instagram Story to share apparent screenshots of direct messages with MGK in which he derided Green, 51, as a “child actor” and told him to “go back to cereal commercials.”

“Stop asking when our child is gonna be born. You the FEDS,” MGK allegedly added in a DM. “Quit calling TMZ and focus on that apology you owe me for speaking on my name in public.”

Fox, meanwhile, has no interest in participating in her exes’ feud.

“Megan wants to stay out of their fighting, she feels it’s their issue, not hers,” a source told Us on March 28. “Megan is focused on the first days with her baby.”

This is Fox’s fourth child. She shares sons Noah, 12, Bodhi, 10, and Journey, 8, with Green. Fox revealed in late 2023 that she had suffered a miscarriage during her relationship with MGK, who has a 15-year-old daughter named Casie.

In November 2024, Fox revealed that she and MGK were expecting a rainbow baby after their past pregnancy loss. 

“Nothing is ever really lost,” she captioned an Instagram post at the time, showing off her baby bump. “Welcome back 👼🏼❤️.”
