Chris Griffin Wikipedia
Stewart Gilligan Griffin is timeless, but his precise age is shrouded in secrecy. It's unclear how old Stewie entered existing. The infant persona from the animated television show "Family Guy" is age-defying. His time on Earth is yet to be discovered.
Stewie, the clever little troublemaker, is impossible to determine from the world. Speculation abounds as to the length of time he has existed. Is he a century old? Or is he fresh to the world? The truth lies only with Stewie! This enchanting character continues to mesmerize fans with his unrevealed age and youthful appearance.
