Brad Pitt tops sex list

Brad Pitt and Megan Fox have topped a list of stars people would allow their partners to sleep with.

The Hollywood stars were voted into the top spot after UK couples were asked which celebrities their partners would let them sleep with without classing it as cheating, known as a 'list'.

Joining Brad on the 'allowed' list for women were 'Alice in Wonderland' actor Johnny Depp, '300' star Gerard Butler, soccer ace David Beckham and 'Twilight Saga' hunk Robert Pattinson.

Male respondents opted for Brad's ex-wife Jennifer Aniston and his current partner Angelina Jolie, who were named second and fifth respectively, with Beyonce Knowles and Jessica Alba taking third and fourth place respectively.

Mark Pearson, Managing Director of Groupola.com, which conducted the survey of 1,198 couples, said: "I think that having a 'list' in a relationship is fine, as long as they are taken in jest and feelings aren't hurt.

"Although, I do wonder if any of the respondents would ever actually follow through with their 'list'. I can't help but think that even if people were confronted with the situation whilst in a serious relationship, they would probably shy away from it!"
