Mario & Karina: Over Before It Began?

Just when we were starting to get comfortable with the idea of Mario Lopez and Karina Smirnoff actually owning up to their couplehood, we get a call from an insider telling us it's all over for the Dancing duo! According to a source extremely close to Team Lopez, Mario started flirting with his date (?) Elena once his party made it into Parc - and Karina utterly lost it! We don't want to report any unconfirmed details about their fight, but our source made one fact unmissably clear - before leaving, Karina took great pleasure in informing Mario that "it's over"!
