Megan Fox Baby Due Date: 5 Shocking Revelations About Saga Blade's Birth And The MGK Co-Parenting Saga In 2025

The widespread curiosity surrounding Megan Fox’s baby due date was finally put to rest in the spring of 2025, when the actress welcomed her fourth child with musician Machine Gun Kelly (MGK), whose real name is Colson Baker. The anticipation, which began with a stunning and unexpected pregnancy announcement in late 2024, culminated in the arrival of a baby girl named Saga Blade Fox-Baker. As of today, December 11, 2025, the focus has shifted from the due date to the complex, yet seemingly successful, co-parenting arrangement between the former engaged couple.

The journey to the baby’s arrival was anything but conventional, mirroring the famously intense and dramatic relationship between the Transformers star and the "Bloody Valentine" artist. The news of the pregnancy itself came as a surprise, described by Fox as "unplanned but a happy surprise," and the subsequent birth confirmed the end of the speculation, solidifying a new chapter for both stars as they navigate a blended family of six children.

The 'Unplanned But Happy Surprise' Pregnancy

The pregnancy was reportedly a surprise for the couple, who had been engaged since January 2022. Fox later shared that the pregnancy was "unplanned but a happy surprise," coming at a time when their relationship was experiencing significant turbulence, including rumors of a split and the temporary removal of her elaborate engagement ring.

The unexpected news reportedly provided a new, grounding focus for both stars, shifting their dynamic from a volatile romance to a shared commitment to parenthood. The baby's arrival was highly anticipated by fans, who had closely followed the couple's intense, "twin flame" connection since they first met on the set of the movie Midnight in the Switchgrass.

The Official Birth Date and Name Revelation

The speculation about the "due date" finally ended when the baby arrived. Megan Fox welcomed her daughter, Saga Blade Fox-Baker, on March 27, 2025. The name 'Saga Blade' immediately sparked discussion among fans and media outlets for its unique and dramatic flair, perfectly fitting the child of the two rock-and-roll-inspired parents.

Machine Gun Kelly, or Colson Baker, was quick to share the news on social media, expressing his joy and even composing a song for the two-month-old baby girl later that year. The birth marked a pivotal moment, not just for the couple, but for the entire blended family, bringing a new sister into the lives of Noah, Bodhi, Journey, and Casie.

Navigating Co-Parenting: Fox and MGK's New Dynamic

Perhaps the most compelling and current aspect of this story, as of late 2025, is the evolving relationship between Megan Fox and Machine Gun Kelly post-birth. Despite the baby's arrival, the couple did not immediately reconcile their romantic relationship. Reports indicated that they had separated weeks after the pregnancy announcement in late 2024, and have since focused on a healthy co-parenting dynamic.

Thriving as Co-Parents, Not Partners

As of the end of 2025, sources close to the couple confirm they are "thriving as co-parents." They have been seen together on family outings, including spending Thanksgiving together with baby Saga Blade and attending events like the L.A. Zoo Lights. This arrangement shows a mature commitment to their daughter's well-being, prioritizing a stable environment over the volatility of their past romance.

MGK has been open about his devotion to his daughters, often sharing rare glimpses of baby Saga on his social media, including a video of her playing a rain drum while he was on his Lost Americana tour. He also brought his 16-year-old daughter, Casie Colson Baker, to the 2025 American Music Awards, demonstrating his commitment to fatherhood across his family.

The Blended Family Reality

The reality for Megan Fox is now one of managing four children from two different fathers, alongside her ex-fiancé's older daughter. This requires a complex network of co-parenting relationships, involving Brian Austin Green for the three boys and Colson Baker for their daughter, Saga Blade. The focus on establishing a peaceful, functional family unit, even without a romantic label, is the latest chapter in their highly public lives.

The saga of Megan Fox’s baby due date has transformed into a story of modern celebrity parenthood. The due date of March 2025 passed with the joyous arrival of Saga Blade Fox-Baker, marking a new era for both Fox and Machine Gun Kelly as they navigate the challenges and rewards of co-parenting their daughter while maintaining a supportive, if non-romantic, connection.
