I had the great pleasure of working with Jooles and her partner at a hotel shoot yesterday. The aspect that made the shoot for me, overlooking the fact that it was a great laugh, was that all of the parties wanted to work together as a team to create the final image and contribute whatever they could to further that goal. It wasn't just a case of the model wanting to look pretty, the partner wanting to make sure nothing untoward happened and the photographer issuing orders for everyone to carry out.
As a result I would have to say if you get the opportunity to work with Jooles then you should jump at the chance but if she says her partner might be able to come along, forget everything you might have read on chaperone threads, get your pogo stick out and start chasing after the possibility.
I'm very pleased with the images we've created together and I hope you get to work with the photographers who will be able to challenge you to the levels you deserve.
