And baby makes four!

"Dexter" star Colin Hanks and his wife Samantha Bryant are expecting their second child, the actor's rep confirmed to ABCNews.com. On Monday, Bryant debuted her baby bump at opening night of her father-in-law Tom Hanks's new Broadway show, "Lucky Guy."

Baby Hanks joins will join big sister Olivia Jane, who was born in 2011.

"A baby's existence for the first three months is a one-way street. One person is doing all the work and the other is crying, sleeping, and pooping," Hanks joked at the time. "[But] since our daughter joined us the spectrum has widened. My job is to recreate moments between people and when you're able to look at moments differently, you get deeper meaning in things."
