Hmmm that's a good question Xassy!
I would say Lilia - she has shown that she has a good feel for comedy during the tour when she's been the perfect foil for Julian Clary - but I think RW looks like he may be a bit too tall for her perhaps.
How about Kristina? She surely deserves someone relatively young and fit who would have a reasonable chance of doing well in the competition after what happened last time....
