I saw Kylie some years ago when she and some other Hungarians were camped out in West Kensington. She was curvy and relatively lean then, and on the basis of it being a good punt, I saw her again some time later (maybe 2 years ago).
Disappointingly she had porked out quite a bit and I'd say leaning more towards the Diane end of the spectrum. As bigman said, she's quite short (def not 5'6") so she can't carry the extra that well. Service wasn't so great either. Not been back.
