Sienna Caught Monkeying Around

 It seems that Sienna Miller doesn�t get a break from newspaper headlines.

Usually it�s over her latest escapade with a new hunk, but this time it seems she�s been canoodling with a stud of the simian variety.

The �Factory Girl� star usually has no shortage of males trying to stick their tongue down her throat but the unsual proposition arose at a quirky shoot for Esquire magazine.

She was asked to blow on the monkey, which she was posing with, in order to grab its attention.

She recalls, "In order to make the monkey respond with you, you have to blow at its mouth - and it'll kiss you."

But the over-zealous creature proceeded to stick its little monkey tongue into Sienna�s mouth.

The Alfie star adds, "I sort of made out with a monkey... It was a sweet monkey but, no, that's too much."

And to finish off the bizarre encounter, the monkey proceeded to urinate on Sienna�s back.
