“13. Wow, my teenager,” Fergie wrote. “I’m saying that with tears in my eyes as I feel like the world is shifting beneath us.” She praised the “kind, silly, and cool dude” he had become before wishing him a happy birthday.
How did Axl celebrate before his birthday?
The Instagram tributes followed an early birthday trip to Universal Studios Hollywood on August 27. Duhamel visited the theme park with Axl, his wife, Audra Mari, their son Shepherd and several of Axl’s friends.
A blended-family portrait from the outing appeared online the following day. Duhamel said the group had enjoyed “an incredible day” celebrating Axl and thanked park staff for giving them “a day we won’t forget.” A large theme park, teenage friends and younger siblings may not guarantee calm, but the photographs suggested everyone survived the itinerary.
One of Duhamel’s birthday pictures also appears to show Axl holding his infant half-sister, Rocca. The image offered a rare look at all three stages of Duhamel’s current parenting schedule: a teenage son, a toddler and a baby.
Some initial reports incorrectly described Rocca as 3 years old and Shepherd as 2. Shepherd was born on January 11, 2024, making him 2, while Rocca arrived in May 2026 and is only about three months old. Axl is Duhamel’s eldest child and Fergie’s only child.
Duhamel married Mari on September 10, 2022. They announced Shepherd’s arrival in January 2024 and welcomed Rocca in May 2026. Fergie publicly supported the latest addition by liking the baby announcement and leaving heart emojis in the comments, a modest social-media gesture that attracted attention because celebrity divorces have trained everyone to inspect punctuation for evidence of conflict.
What have Fergie and Josh Duhamel said about co-parenting?
Fergie and Duhamel married in January 2009. They welcomed Axl on August 29, 2013, when he weighed 7 pounds, 10 ounces. The couple announced their separation in September 2017 and finalized their divorce in November 2019.
Since then, both have presented a consistent account of their co-parenting arrangement. During a March 2026 appearance on The Skinny Confidential podcast, Duhamel acknowledged that he and Fergie have “different views of the world” but said they maintain “a great relationship.” He also praised the connection between Fergie and Mari.
The actor repeated that assessment on The Megyn Kelly Show later that month, saying “everybody is just copacetic.” He called Fergie “a great mom” and said her positive relationship with Mari was what mattered most to him.
The birthday posts fit that account. Fergie and Duhamel shared separate tributes rather than staging a joint statement, but both focused on the same qualities in their son. He described Axl as compassionate and thoughtful; she called him kind, silly and cool.
For a family spread across two households and three children with a 13-year age range, the celebration looked notably straightforward. Axl got a theme-park trip, photos with his siblings and two proud Instagram slideshows. Becoming a teenager rarely arrives with this much public documentation, though being the child of Fergie and Josh Duhamel was never likely to be a low-profile arrangement.
