Kristen mentions Rob in Interview With Italian Newspaper

I: Com’è stato, rispetto ai baci con Pattinson? (Asking her the difference of kissing Dakota and Rob)
K: "What can I say? Rob has a bigger mouth?"

I:"Last question: Do you want to clear up your relationship with Robert Pattinson?"
K: "No, I don't. I just can say that with Twilight we all have become really close and what people say about us ends up debasing our relationships"

I: "So are you telling me you are just good friends?"
K: "No, that's not what I said"
