Sienna was spotted on the set of her new film Hippie Hippie Shake with her "good friend" and "house guest," Rhys Ifans. The two were also caught getting cozy at a wedding over the weekend, so we're not sure how much longer they can deny their romance. Sienna was also sharing peace and love with her co-stars, the Irish actor Cillian Murphy and the indie film darling Max Minghella (son of acclaimed director Anthony Minghella). The trio filmed was seen in central London's Grosvenor Square, re-creating a famous protest from 1968. Lucky for Sienna, this time she got to keep her clothes on!
