The `Scott Pilgrim vs. the World` star and his wife Brady Cunningham have announced they are expecting their first child together.
And Jason has decided to grow a moustache in preparation for his new arrival so he can embarrass his child in years to come.
He told talk show host Jimmy Kimmel: "I`m expecting a child in December. I decided to grow out this moustache, so when we take photos, my boy or girl, whatever it is, they will be embarrassed.
"So I am now thinking of ways to embarrass my unborn child."
The 30-year-old actor has been inspired in his quest to embarrass his child by his own father composer David Shire`s sizeable moustache.
Speaking about his baby photos, he explained: "I would show my friends, `Look at my father`s moustache, how terrible is that?!` "
Jason - whose mother is `Rocky` star Talia Shire - and fashion designer Brady married in a low-key ceremony at their San Fernando Valley home in July 2009.
