"We are very excited. We think our 1-year-old Cecilia is excited too, but she can't talk yet so we can't be sure," the couple joked in a statement.
This is great news for the couple, especially since Walton apparently has a bad case of baby fever. "I walked in on my husband talking about having a third child and we haven't even had a second yet. What the hell you guys??" Delfino tweeted June 6.
Delfino will soon be seen on the new series Friends with Better Lives while Walton will star on the small-screen adaptation of About a Boy, one of TVGuide.com's most-anticipated new comedies. The comedies are set to premiere midseason on CBS and NBC, respectively.
