Fancy a shag, mates? Well, odds are that if you’re either apparently wealthy or an up-and-comer in the realm of the starfucking famous, Sienna Miller has you covered. This is no exaggeration, for Sienna’s well-known promiscuity has translated into an immeasurable and integral part of England’s #1 ranking against all other major western industrial countries within “an international index measuring one-night standsm total numbers of partners and attitudes to casual sex.” New Scientist magazine has published the three-year study with further evidence of a certain habitual homewrecker’s influence:

[These] findings are reinforced by earlier research showing that the British are more likely than other nationalities to have “stolen” other people’s lovers. A third of British men are in relationships with women they have poached from other long-term relationships, he found.

Among British women, 28% have apparently poached their other halves rather than formed relationships with single men. Only 17% of men in America had poached their girlfriends. In France only 10% of both men and women were poachers. In Germany the figures were 17% of men and 14% of women.

Thanks to Sienna, the U.K.’s slut-quotient easily beats out the rest of the promiscuous, mate-stealing top five: Germany, Netherlands, Czech Republic, and Australia. The U.S. slides in at #6, followed by France, Turkey, Mexico, and Canada. So, let’s take a look at the little nympho’s more notable conquests since 2005:

David Neville, Jude Law, James Franco, Jamie Burke:

Orlando Bloom, Hayden Christensen, P. Diddy, Rhys Ifan, Balthazar Getty:

This doesn’t even begin to account for Sienna’s rumoured liasons with many other actors and models, including Leonardo DiCaprio, Nico Malleville, Daniel Craig, and (most recently) Josh Hartnett. England owes you a great debt, Sienna Miller. Not to mention an STD clinic named in your honour.
