Billy Crudup and Mary-Louise Parker’s Son, 21, Towers Over his Dad While Strolling NYC originally appeared on Parade.
Williams Atticus Parker, the 21-year-old son of Mary-Louise Parker and Billy Crudup, is all grown up. WAY up. The young director is already towering over his father!
The father-son duo was spotted by the Daily Mail strolling the streets of New York City together earlier this week. Both sporting khaki pants, Billy chose an Oxford shirt for the occasion, while Parker had a white tank and an unbuttoned shirt. With his dark hair and dark eyes, the rising filmmaker looked like a true fusion of his parents.

After Watts and Crudup got married, Parker was candid about sending the couple her hopes for a happy marriage.
“I wish them well,” she told the Guardian. “And absolutely, I honestly of course wish them every happiness because that’s my son’s father. So I’m happy for them. I’m happy they found each other.”
These days, Crudup is busy starring in The Morning Show, which just released its season 4 teaser trailer.
