Josh and Anna Duggar Are Expecting Baby No. 4

It's déjà vu time: There's another Duggar baby on the way.

Josh and Anna Duggar, of 19 Kids and Counting fame, are expecting a baby next year. It will be the couple's fourth — and likely M-named — child, for those keeping track at home. They already have a 5-year-old daughter, Mackynzie, and two sons, Michael, 3, and Marcus, 1.

"We are so excited to announce...we're pregnant! #4andCounting #BlessingfromTheLord @joshduggar #19Kids," Anna tweeted on Tuesday.

Of course, this isn't the only current pregnancy within America's most fecund family. Josh's sister Jill is also expecting her first child — and probably not her last — with husband Derrick Dillard.
