A Hippie Hippie Shake post-production crew had to fluff up Sienna Miller's muff to make it suit a film set in '60s London. "Sienna was an absolute star throughout filming and her performance was flawless," an insider told the Mirror. "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." Wardrobe tried covering Miller's minge with a merkin but it looked...like a wig – and a weave might have been too labor-intensive. So it was CGI to the rescue. "Sienna's private parts were digitally enhanced," said the insider, "giving her a rather unruly, loud-and-proud bush." (Female First; photo via Egotastic!)
