Jo Dee Messina is standing by her friend Wynonna, who was arrested last Friday for driving under the influence. "Though I don't condone it, I also know her as a person, and I'm sure she's beating herself up about it," says Jo Dee. "And what anybody else says is unnecessary beating,'' she said. ''You're talking about somebody who has given so much positive for so many years. I just beg that people don't fry her. If she needs a friend, she can just call me. She was human for a moment.''
