'Dancing with the Stars'' Karina Smirnoff optimistic about her 'Situation'

We know he's got his "Jersey Shore" obligations, but  Mike "The Situation" Sorrentino better hope for natural ability to make up for his abbreviated rehearsal time for his upcoming "Dancing with the Stars" turn. He and partner Karina Smirnoff have yet to step out on the floor together -- or meet, for that matter.

MTV reports that Smirnoff, while excited about her new partner, is a tad nervous about the duo's lead time before the series' Sept. 20 premiere, which could be as short as five days.But the win-less "DWTS" pro remains optimistic.
