Jason SchwartzmanJason Schwartzman is getting ready for diaper duty. The actor announced on 'Jimmy Kimmel Live!' Wednesday that he and his wife of one year, clothing designer Brady Cunningham, are expecting their first child together.

"I'm expecting a child in December," he said. "I decided to grow out this mustache, 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 'Scott Pilgrim vs. The World' actor joked.
