Fox welcomed her fourth baby, a daughter, in March with her former fiancé Machine Gun Kelly, 35. She is also mom to sons Noah, 12, Bodhi, 11, and Journey, 8, whom she shares with ex-husband Brian Austin Green.

The Jennifer's Body alum welcomed her daughter, her first with her ex, on March 27. Kelly shared the exciting news on his Instagram as he posted a video of himself with his newborn daughter.

"She’s finally here!! our little celestial seed 🥹💓♈️♓️♊️," Kelly wrote in the caption. "3/27/25."

In the black-and-white video, Kelly could be seen holding his baby daughter's hand, stroking her fingers.

Fox and MGK, who got engaged in January 2022, called it quits at the end of November, not long after announcing their baby on the way.

A few months after Kelly and Fox welcomed their baby girl, a source exclusively shared with PEOPLE that the former couple is not together despite the rapper staying at Fox's house occasionally.

The source revealed that Fox and MGK are "committed to being present for their daughter," which is why he's been staying at the house "part-time."

"Megan and Colson are not back together," the insider told PEOPLE. "Their relationship remains focused strictly on coparenting their baby girl. While Colson does occasionally stay at Megan's house, it's only part-time and solely to spend time with the baby."

"They're committed to being present for their daughter, but they're not living together or romantically involved," the source added.
