Tammy: (on appearing in Gypsy) I did have a lot of anxiety taking my clothes off, standing there "naked." I am really covered up. It's like a bathing suit. The more I do it, the more I get over it. I am over the whole thing, I don't want to ashamed of my body or being naked. This is opening me up and its making me grow up a lot, too.
Tammy: No one can tell me what to think about God. I know that he loves me, and I know that he's with me always. I feel God has chosen me to do something really special. It's all about peace, love and happiness.
