This is definitely an interesting family dynamic.
Kimberly Stewart, 36, just shared some adorable new photos on Instagram of her 5-year-old half-brother, Aiden Stewart, playing with her 4-year-old daughter Delilah Del Toro (yes, Benicio Del Toro is her father).
That's right, Rod Stewart and wife Penny Lancaster have another son that's almost exactly the same age as the singer's daughter's kid. Stewart is dad to 8 children, ranging in age from 53-5. He put his oldest daughter, Sarah Streeter, up for adoption in the '60s.
Caught up on the family tree? O.K., back to these super cute pics!
Kimberly, her dad and her stepmom are all on vacation together in Paris right now ... and have been sharing some great family snaps on social media.
In one (top), we see Delilah and her 5-year-old uncle, Aiden, in front of the Eiffel Tower. In another (above), Stewart and Del Toro's daughter poses in front of the French landmark, flower in hand.
Lancaster shared a precious pic on her Instagram page as well (below), showing the two kiddos on a carousel in the city. "Easy riders," 45-year-old former model captioned the pic.
"I honestly never, ever thought that I could love anything as much as I love her," Kimberly said of her daughter in an interview with Hello last year. "I had her at the right time. I got all the partying out of my system and I just wanted to be with her. I've been a stay at home mother since she was born and I've loved every second."
"Even I struggle to keep up," she added of her big family -- which includes brother Sean, and seven other half-siblings.
