Sienna Miller was getting cozy with Orlando Bloom at the Cartier International Polo match this weekend. They used to date in 2001 and I guess it was easy for her to get comfortable with him as they were reportedly really close and even kissing at one point. I doubt it was a real kiss. I think he made a point to go to Australia last month to win back Kate and besides, as angry as Sienna may be, I doubt she is making out in public with other famous men. She was head over heels for Jude so her heart was truly broken. By the way, Jude is still insisting they are engaged although Sienna has not been wearing her ring for a week.
