Sienna Miller is rumored to be romancing Keira Knightley's ex-love, Jamie Dornan.
The stunning actress - who has been linked to 'Star Wars' hunk Hayden Christensen since splitting from fiancee Jude Law - has allegedly met the Irish model for a string of secret dates.
Sienna and Dornan - who split from 'Pride and Prejudice' beauty Keira last year - have reportedly been meeting at London's swanky Electric bar since becoming neighbors in the capital's Notting Hill area.
Onlookers spotted Sienna "flirting outrageously" with Dornan, according to a report in Britain's The Mail newspaper.
One of Keira's pals says the screen beauty will be furious Sienna has the hots for her ex.
The source says: "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."
