Tia, Tamera, and there whole family are devoted Christians, and they take it very seriously. They where WWJD bracelets (What Would Jesus Do), and in some of there photos, you can see them. You just have to look closely.
Tia once said, "Just so you all know, I keep my pictures of my friends in my bible"
Last year, Tia and Tamera travelled around in America, visiting churches and telling about their Christianity to other people, both young and old.
Before they shot each episode of "Sister, Sister" they had a prayer session.
