Gary Chapman, author of the New York Times best-seller The 5 Love Languages: The Secret to Love That Lasts (Northfield Publishing/Moody Publishers), appeared on Oprah’s Lifeclass to discuss the love languages. Timed just ahead of Valentine’s Day, Chapman appeared on the show yesterday and will appear again today. After the Oprah appearance, the book ranked at No. 2 on Amazon's best-sellers list.

On the show, Oprah takes a quiz to learn her love language, and Chapman explains how knowing which love language your spouse speaks can transform your relationship. The View co-host Elisabeth Hasselbeck explains how the book changed her marriage, and couples demonstrate how considering their spouse’s love language brought their marriages back from the brink of divorce.
