'19 Kids and Counting' Season 8 video: The Duggar girls head to the recording studio



On Tuesday's (April 29) episode of  "19 Kids and Counting," the oldest Duggar girls head to the recording studio. No, they're not jumping into the pop star arena. They're recording the audio version of their new book, "Growing Up Duggar."

In this  Zap2it exclusive clip, we get a behind-the-scenes look at Jill, Jinger, Jessa, and Jana working with a recording engineer. It's not as easy as it looks, and some of them are better than others. The girls logged more than 200 hours putting this book together, and they hope it "touches lives."

"19 Kids and Counting" airs at 9 p.m. ET/PT Tuesday on TLC.
