The Denise Richards and Richie Sambora showed up the first time in public, hand-in-hand at the Fashion Rocks concert in New York City. Richards wore a huge rock on her left hand - are they engaged?

Richards' attorney explained, "It's not true, they are only rumors. No engagement as of yet."

The couple have been only dating for a few months. No plans for getting hitched.
