Promoting their new flick I Am Number Four, the costars -- and real-life couple -- posed for pics before meeting hundreds of fans who camped out at the mall to see the stars and get their I Am Number Four t-shirts signed.
Last week, rumors flew that Alex and Dianna were engaged, but reps for both stars have since denied the claims, and Dianna personally took to her blog to comment. "I have been getting a lot of questions about things that I don't feel the need to explain or talk about," she says.
