Mandy Admits To Having Short Romance With Billy Crawford
A fan asked Mandy Moore on her official site's message board if she had dated Billy Crawford, who had sung the Pokemon theme song. Mandy replied, "Talk about bringing the past up. LOL. Yes. we met on the *NSYNC tour. I was 15, he was 17. It only lasted for a few weeks. What a talented singer he is."
