Kimberly Stewart - daughter of wrinkly rocker Rod - has opted to give her baby daughter Delilah a double-barrelled surname.
Kimberly had her little girl after what was believed to be a 'no strings fling' with Benicio del Toro, and their daughter's birth has been certified in an LA registrar's office as Delilah Genoveva Stewart del Toro.
Kimberly, 30, and Benicio announced they were to be parents back in April, but Sin City star Benicio soon admitted they were not actually a couple. His spokesperson did however confirm he WAS the dad of Kim's unborn baby, and was very supportive of her pregnancy.
Kimberly delivered little Delilah just months after her step-mum Penny Lancaster and dad Rod celebrated the arrival of their new baby, Aiden. Rod, 66, has EIGHT children altogether.
Bet it gets crowded round their dinner table come Christmas...
What do you think of Kimberly's decision? Did you choose to make your children double-barrelled?
