Gwyneth Paltrow makes "orgasmic noises" when she has a pedicure.

Sophy said: "When I was working at the nail bar, a couple of celebrities used to come in and the one that really left me star-struck was Gwyneth Paltrow.

"I was really nervous and I remember doing her pedicure and thinking, 'I've got Gwyneth Paltrow's foot in my hand!' Somehow I managed to keep my cool. It helped that she was really nice too, although I was giving her a foot massage and she was making all these orgasmic noises."

While Sophy had a good experience with Gwyneth Paltrow, it wasn't so pleasant working for "very difficult" Christina Aguilera.

Speaking to LOOK magazine, she said: "I remember being called up to do Christina Aguilera's nails the night before she was going on [TV show] 'CD:UK'.

"These big American celebs were used to getting their nails done at the click of a finger and they would come to London and expect the same. It definitely wasn't the best experience - she was very, very difficult."
