Kimberly Stewart is celebrating her son’s first birthday!

The 46-year-old model and socialite, who is the daughter of rocker Rod Stewart, recently took to her Instagram Story to share the first glimpse of her baby boy in honor of his birthday.

In the photo, the little one, whose face is covered with a white heart emoji, is sitting in a highchair while wearing a dark blue shirt and plaid shorts as he’s surrounded by blue balloons. A small homemade birthday cake decorated with icing, blueberries, strawberries, and a number 1 candle is placed on the tray in front of him.

This is the first time Kimberly has posted anything about her son on social media. Back in March 2025, Kimberly announced that she was pregnant with her second child, but she never officially revealed when he was born.

Kimberly is also mom to 14-year-old daughter Delilah, whom she shares with Oscar-winning actor Benicio del Toro. Kimberly‘s son is Rod‘s fifth grandchild. He has eight children total, and has been married three times. He is currently married to model Penny Lancaster, 55, and they have been wed since 2007.

Back in 2023, Kimberly, Rod, Benicio, and Delilah took a vacation together in Puerto Rico.
