Rocker James Durbin is set to become a dad for the second time later this year (14). The American Idol alum's wife Heidi will give birth in November (14). The couple tells People.com, "We're looking forward to even more laughter in the house and those silly baby expressions." Durbin and Heidi married in 2011 and have a four-year-old son, called Hunter, who is "very excited". The singer adds, "He wants a little brother to play Legos with. Since we spaced them apart from each other, Hunter will probably be a big help."
