Tiffany Thornton chatted with Hollywood Life of qualities Demi Lovato‘s should have: ‘I think Demi needs to be with someone who has a very strong faith. A guy that respects her and can make her laugh. She gets bored easily. We both are Christians. We both love the Lord. For us, being able to focus on that helps a lot.’ Demi mostly recently dated Joe Jonas and Trace Cyrus.
