Bristol Palin and Mark Ballas, the reunited season 11 duo, ham it up the most -- with Ballas wearing his glasses and the two blowing imaginary smoke off of their finger guns.

Pamela Anderson and Kelly Monaco are also looking cozy with their new partners, Tristan McManus and Val Chmerkovskiy. And Cheryl Burke and Emmit Smith are happily reunited.

Missing from the photo shoot are Kirstie Alley and Maksim Chmerkovskiy -- perhaps too busy practicing? -- and wildcards Carson Kressley, Kyle Massey and Sabrina Bryan. One of the latter three will officially join the cast after an announcement on Aug 27.
