No, sorry.
The VS ad doesn't suggest she's touring. If it's the same girl, where is she actually working? Perhaps check if you can secure a booking in London and Sheffield on the same day. My gut feeling would be that the VS uses ripped pics so high chance of B&S. The pics are heavily shopped so if you did get to meet the same girl, she's going to be a lot older. Still, if you're prepared to walk (as you said in the other thread) then no harm in checking her out and being pleasantly surprised.
