Josh Gracin and his wife, Ann Marie, welcomed the fourth addition to their family this week. Daughter Isabella Sophia Gracin was born yesterday afternoon, Nov. 12, in Nashville. Isabella joins sisters Briana, 6, and Gabby, 23 months, and brother Landon, 3. "She's the biggest of all our babies, outweighs the others by a pound and a half and is an inch longer than our other three at birth," Gracin told People. "With three girls and one boy, I'm afraid our son Landon is going to suffer the same fate as me growing up with four sisters. He's going to have to learn to hold his own. But everyone is doing well and it's amazing to have a new member in the family."
