Flustered Sienna, 26, seemed in a hurry to escape the attentions of Hollywood's ever-present paparazzi pack after lunching with former love, Welsh actor Matthew Rhys, 33, star of US drama Brothers and Sisters at a Hollywood restaurant.
Getaway girl: Sienna Miller, seen here with Welsh actor Matthew Rhys, appeared keen to avoid the paparazzi's lens in Los Angeles, yesterday
The pair met on the set of the Dylan Thomas biopic The Edge Of Love and were reported to have enjoyed a number of dates last year during filming before she moved on to current love, Welsh actor Rhys Ifans, 39.
After leaving the restaurant with Rhys, a summery looking Sienna dressed casually in a yellow dress, a pretty look spoilt only by her battered grungy boots, soon found herself being trailed by photographers.

But the young starlet is fast discovering that life in Hollywood requires a certain amount of resourcefulness.
When some guys in a passing people carrier, seeing her distress, slowed down to offer her a ride, she was so reassured by their claim of "we aren't murderers or anything, you'll be safe", that she hopped in.
The car then made a high speed departure complete with a tyre screech as Sienna said: "Go, go, go!"

Hop in: The driver reassured her they were not 'murderers' and another passenger gave her a helping hand to get in the vehicle
Sienna's boyfriend Rhys Ifans, 39, travelled back to London while she films blockbuster GI Joe with Dennis Quaid and Channing Tatum in Los Angeles.
The couple, who have been dating for nine months are rumoured to be engaged and planning a summer wedding.
And one person who isn't surprised that stunning Sienna has found love with the somewhat scruffy Rhys is his proud mother Beti-Wyn Evans.
Beti-Wyn, 62 said: "Yes, I know what they say - that Rhys is this lanky, gawky guy from North Wales and he's hooked up with one of the world's most beautiful women, but my son is gorgeous too, you know.
"He's a wonderful person and he's got charm - and what woman doesn't love charm?"
Beti-Wyn, lives with retired husband Irwyn near Ruthin in North Wales, where Rhys and Sienna are reported to be house-hunting.
She added: "They adore each other and I'm so pleased for them…They make a fantastic couple."
