Quick Scoop

  • Diane Keaton became a mom in her early 50s, when she adopted her daughter Dexter in 1996, shortly after Dexter’s birth in December 1995.
  • Her son Duke was born in February 2000 and was adopted in 2001, also when he was still a baby.
  • So, in simple terms: both of Diane Keaton’s kids were adopted as babies, within roughly the first year of their lives.
