"She sees it in me, and I see it in her, and we're stronger now because of it."
The American Pie star and his actress-author wife Jenny Mollen, 34, welcomed son Sid into the world on 15 February. And there is no doubt that he has transformed their lives.

"Ask me again in a couple of years when the kid is milking me, and it's just horrible, and he's running around and it's exhausting."
Not that becoming a father has changed Jason completely — he is still addicted to reality TV.
"What I've learned from fatherhood is that having a son cannot, did not, change my love for The Bachelor," he admitted with a laugh.
"I thought that having a son would make me grow up when it came to my TV habits, but I love The Bachelor even more after having a child."
