And speaking of Keira Knightley, it looks like Sienna Miller has been chasing Keira Knightley's ex, Irish model, Jaime Dornan. The Post Chronicle reports that Sienna has been focussing her attention on Keira's former flame since moving back to London.

The gorgeous actress, who has been linked to 'Star Wars' hunk Hayden Christensen after splitting from fiance Jude Law, has allegedly gotten together with Dornan for a string of secret dates.

Sienna and Jamie, who split from 'Pride & Prejudice' babe Keira last year, have reportedly been seen at London's swanky Electric bar often since becoming neighbours in the capital's Notting Hill area, according to a published report.

Onlookers reportedly spotted Miller "flirting outrageously" with Dornan, Britain's Daily Mail reported on Sunday.

One of Keira's buddies indicated that the Knightley will be furious Miller has targeted her ex.

The source said: "Keira still holds a flame for Jamie ... There is every chance that he and Keira might one day get back together, so she will be spitting feathers that Sienna is trying to get her mitts on him."

I don't know about you, but I was under the impression that Sienna Miller was all over Hayden Christensen. So either the reports are wrong (which wouldn't be a surprise) or Sienna Miller is pretty slutty (which wouldn't be a surprise).
