In a heartfelt post on her Instagram Stories, Kimberly posted a charming image of her little boy enjoying a birthday treat. The toddler was depicted in a highchair, clad in a dark blue shirt and plaid shorts, surrounded by a cheerful array of blue balloons. A delightful cake, adorned with white frosting, fresh blueberries, strawberries, and a prominent number one candle, sat before him, capturing the simple joy of the celebration.
The announcement of Kimberly’s second pregnancy came in March 2025 when she revealed the news alongside a series of snapshots showcasing her baby bump. Dressed in a fitted floral dress, she embraced the moment outdoors, sharing her excitement about expecting another child. Accompanying the images, she indicated the sex of the baby by adding, “Baby boy coming soon,” alongside a blue heart emoji, signalling her joy at the arrival of another son.
In response to the announcement, Kimberly’s stepmother, Penny Lancaster, expressed her delight through a message on her own Instagram Stories. Re-sharing one of Kimberly’s pregnancy photos, Penny, who has been married to Rod Stewart since 2007, wrote, “So happy you’re becoming a mum again,” showcasing the family’s supportive spirit during this new chapter.
This new addition brings the number of Rod Stewart’s grandchilden to five. Kimberly also has a 14-year-old daughter, Delilah, whom she shares with ex-partner Benicio del Toro. Delilah, born just a day after her mother’s birthday in 2011, recently made headlines for making her red carpet debut alongside her father at the prestigious 2026 Actor Awards.
At the awards ceremony, Benicio del Toro, 59, was seen attending in support of his film One Battle After Another, with Delilah by his side. The teenager looked radiant in a long, off-white, sparkly dress, complete with a matching rosette, as she posed alongside her famous father. Their appearance marked a significant moment for Delilah, who was celebrated not only for her lineage but also her growing presence in the public eye.
While this was Delilah’s first experience on the red carpet, her family has previously shared glimpses of her life on social media. In February 2023, Kimberly posted a touching family photo of the trio—herself, Delilah, and Benicio—during a trip to Puerto Rico, the birthplace of her ex-partner. The photo captured a rare moment of familial togetherness, with Delilah standing between her parents while Rod posed at the end, showcasing the warmth and unity they share despite their past separations.
As Kimberly celebrates the first birthday of her son, it is evident that family remains a central theme in her life. The support and joy of her extended family, including her famous father and stepmother, highlight the importance of togetherness during significant life milestones.
Amidst the hustle and bustle of celebrity life, Kimberly Stewart’s journey reflects both the challenges and joys of motherhood, as well as the bonds that keep families connected. With her daughter now stepping onto the public stage and her son growing up, it will be fascinating to see how their family evolves in the coming years. As she navigates motherhood with grace, Kimberly continues to inspire many through her candid moments shared on social media, reminding followers of the beauty in family celebrations and the simple pleasures of life.
