Sienna feels the force

Sienna Miller has been photographed passionately kissing 'Star Wars' hunk Hayden Christensen.
The 'Factory Girl' co-stars - who have been at the centre of romance rumours for weeks - locked lips as they sat in a parked car near Hayden's home in Canada.
Unaware anyone was watching, the heartthrob actor moved in for a passionate smooch confirming speculation they are an item.
Meanwhile, Sienna - who dumped Jude Law earlier this year - has reportedly been warned to slow down and take a break from partying.
Friends allegedly fear the 24-year-old's challenging work schedule and hectic social life will eventually take its toll.
One pal told Britain's Daily Mirror newspaper they talked to the actress after she embarrassed herself in front of actor Sean Penn at a star-studded bash.
The friend said: "She's partying hard, some of us would say too hard. We sat her down and told her she needed to count to 10 and cool it.
"There was a scene with Sean Penn in the bar where she was being a little too familiar and we knew it was time to have a word."
The friend added: "People need to remember she's still very young and impressionable.
"And the fall out from Jude has left her very bruised."
