Gwyneth Paltrow is struggling to plan the perfect yoga lesson - as a fan has paid $55,000 (GBP30,000) for a stretching session with the actress. The lesson was snapped up by the star-struck health fanatic at a charity auction in aid of British charity The Prince's Trust's 30th anniversary. Paltrow is now desperately thinking of ways to create a masterclass which will be worth the staggering amount of money. She says, "Someone's spent a great deal of money on it so I'm going to have to really come up with an excellent plan. "Unfortunately I can't do it in the nude or anything to make it really exceptional but I will try and come up with a good plan."
