Surprise! Michelle and Jim Bob Duggar are having a baby. Their 20th.

When Michelle made the announcement, Jim Bob quipped, "I don't know how it happened." With more than a decade's worth of time spent pregnant, Michelle definitely knows what she's in for. And she admitted that after waiting longer than usual since her last baby, she and Jim Bob, who are also grandparents, thought Josie might have been their last. But phew, they got pregnant again and are just so excited! Watch them talk about their growing family now.
