Sienna Miller’s romantic trysts with celebrities have gotten a lot of media attention. Most recently, the paparazzi spotted her with Bennett Miller and speculated their affair would ring true. When she appeared in London city last year, wearing what seemed like a round diamond engagement ring with halo of small diamonds, people assumed that couple got engaged. Sienna Miller wore the round diamond ring on the fourth finger of her left hand. Since people wear engagement rings on the left hand finger, the one between the pinkie and the middle finger, it sparked a media hype as to whether she got engaged to Bennett. The reality of it was something completely different though. As it turned out, she had mistakenly left a prop ring on her ring finger after a London show. It was actually part of her costume for the stage revival of “Cat on a Hot Tin Roof”. She actually rushed out after her act in the show for a dinner and forgot to take the prop jewelry off her finger. Sienna’s publicist later revealed that it was a mistake on her part and that there was no engagement as speculated.
