Meg Ryan's son Jack: 10 pounds

Actors Meg Ryan and Dennis Quaid divorced after 10 years of marriage in 2001, but not before the two had a son, Jack, who weighed a whopping 10 pounds at his birth in 1992! Not surprisingly, Jack grew into one big guy, towering over his 5'8" mom by the time he was in high school. The now-20-year-old aspires to follow his parents into acting. Audiences can catch him on the big screen for the first time in the blockbuster "The Hunger Games."
