Sienna Miller has reportedly dumped Hayden Christensen to rekindle her on/off romance with Jude Law.

The actress, who met the 'Star Wars' actor on the set of their new movie 'Factory Girl', is said to have flown to Los Angeles last Friday to meet up with the 'Alfie' star.

Since arriving in the city, Sienna has been staying with Jude, and his four children, in a rented house in Topanga Canyon.

The pair were snapped getting into a car in the area and rumors are now rife they are an item again.

Meanwhile, Sienna is planning to quit London and move to New York.

The 24-year-old actress was recently spotted house-hunting in the plush Chelsea region of the city and was seen looking at an apartment in Harrison Ford's building.

A friend of Sienna's said: "She wants to buy an apartment there."
