Mandy to stay mum on relationship

Mandy Moore won't talk publicly about her relationship with Scrubs star Zach Braff, having learned her lesson in her previous high-profile relationship with Andy Roddick. "I'm an open book, to a fault, and that's fine when you're together but then when you're not anymore, and people think they know why, it's such a bummer. I ended up wishing I'd never opened my mouth," the American Dreamz star said.
