LONDON: Sienna Miller wishes she was more like her pal Keira Knightley - because the Pirates of the Caribbean star always keeps her private life out of the media.
The Factory Girl actress, who starred alongside Knightley in The Edge of Love in 2007, has become a paparazzi target after a stream of controversial love affairs.
She has dated actors Jude Law and Rhys Ifans, and was at the centre of a scandal last year (08) after she started romancing married father-of-four Balthazar Getty.
Miller realises she has made mistakes, but insists she is still learning and doesn't possess the ability to make smart choices - unlike Knightley, who has managed to avoid such attention.
She says, "I haven't been as bright in some of the decisions I've made. Keira's just a more evolved person. I feel we live in the kind of culture now where you have to be very smart to navigate the right way, and I just don't have those smarts. I think with age and time it will change, but I can't obsess about it."
