"I am so excited about the newest member of our family," says Turner. "I can't wait to hold him or her for the first time." The baby will join the couple's 2-year-old son, Hampton, whom Turner has described as "full of energy and such a delight." The "Everything Is Fine" singer, whose wife plays keyboards and sings backup in his band, says having Hampton in their lives "makes you richer as a person." Turner is currently featured on the "Blessings" page of PEOPLE magazine's Country Special issue, in which he reveals the five things for which he's most thankful. The issue is on newsstands now.
