Sienna Miller has become so terrified of the British paparazzi she is considering turning her back on acting.

The Alfie actress became a prime target for photographers when her partner Jude Law's infidelity grabbed newspaper headlines in July (05).

And, even though Miller has forgiven the CLOSER star, she is still struggling to cope with the constant invasions of her privacy.

The 23-year-old says, "London is getting worse and worse. What I have most of the time is me running down the street in pitch black with eight grown men sprinting after me.

"The way it has been for a while now... it's reaching a level where it's actually not worth it to be an actress. I love my work, but I can't live my life like that."
