Megan Fox’s family just got bigger.
The actress has given birth to her fourth baby, her first with ex Machine Gun Kelly and the rapper’s second, he announced on Instagram Thursday.
“She’s finally here!! our little celestial seed 🥹💓♈️♓️♊️,” he captioned a black-and-white video showing him holding the newborn’s hand. “3/27/25.”
When the on-again, off-again couple began dating in 2020, Fox, 38, was already the mother of three children with ex-husband Brian Austin Green.
She and the “Beverly Hills, 90210” alum, 51, co-parent Noah, Bodhi and Journey.
MGK, for his part, shares a 15-year-old daughter named Casie with Emma Cannon.
The rocker, 34, revealed during a May 2022 performance that Fox had suffered a miscarriage while they were attempting to start a family.
He sang “Twin Flame” at the Billboard Music Awards and dedicated it to his “wife” and their “unborn child.”
In November of the following year, Fox wrote about the pregnancy loss in her poetry book, “Pretty Boys Are Poisonous.”
She also opened up to WWD about the experience being “much harder” to process than her previous ectopic pregnancy.
In November 2024, the “Transformers” star told her Instagram followers that she was expecting again, debuting her baby bump in black body paint.
“nothing is ever really lost,” she wrote on Instagram at the time. “welcome back.”
Later that month, she and MGK called it quits over the musician allegedly having “text messages involving other women” on his phone.
A source told Page Six at the time that “Megan is a strong, independent woman and doesn’t need a man in her life.”
Fox and MGK were last plagued by cheating rumors in February 2023 when she deleted their photos from social media; they were subsequently spotted attending couples counseling.
The brunette beauty clarified in a March “Call Her Daddy” podcast episode that she and the “Bloody Valentine” artist were no longer engaged, two years after he got down on one knee.
The pair had been dating for less than two years before his January 2022 proposal.
