Sienna has pubic hair enhanced for film?

Sienna Miller had her pubic hair digitally enhanced for her new comedy drama Hippie Hippie Shake, say reports.

According to The Mirror, producers altered Miller's appearance so that nude scenes in the 1960s-based movie would look more authentic.

"The film is set in the swinging '60s when fashion was wild and body hair even wilder," said a source.

"Unfortunately, Brazilians weren't common in the '60s and Sienna's part involved one or two nude scenes - meaning that her grooming habits were on full display."

They added: "Sienna's private parts were digitally enhanced, giving her a rather unruly, loud and proud bush.

"All the cast had a good giggle about it and stoical Sienna happily played along."
