Bloomers - doesn't seem like it will be the Paso either, although I agree Derek would have done a great one.
Here are a few more to add to the guesses out there based on pictures.
NeNe and Derek - Jazz - this one seems pretty positive and I think the dance where the height difference won't matter at all.
Candance and Tony - possibly Quickstep
Drew and Witney - possibly Cha Cha
Charlie and Peta - possibly Rumba
These could turn out to be all wrong, and we will see for sure on Monday.
