Fashion industry and tabloid favorite Sienna Miller is fighting rumors that she is involved with a co-star in her latest London play. She stars in her latest role in London’s West End soon alongside Joe Armstrong, but insists there is no offstage chemistry between the two despite the celebrity news and gossip to the contrary. “I’m single! Poor Joe is like, ‘What’s going on?’” she says, “We all find it ridiculous and laughable.”
In January, Miller split with actor Jude Law, and says that the break-up was “amicable and mutual.” The two had been together just over a year this go-round. They originally began dating in September 2003, were engaged on Christmas 2004, and split up in July 2005 after Law was caught in an affair with his children’s nanny. The two briefly reconciled, but broke up in November of 2005.
