Showing off a snazzy new hairdo, Sienna Miller was spotted out getting pampered at a hair salon in Mayfair on Thursday (June 24).
The "Layer Cake" cutie looked darling in a blue and white striped sleeveless top as she passed by awaiting paparazzi following the beauty session.
And while she was able to tend to the day's appointment, Miss Miller was a no-show at Sir Elton John's annual charity ball in Windsor.
Explaining her reason for skipping out on last night's glamorous UK fete, Sienna told press, "I can't make it, I have glandular fever."
Enjoy the pictures of Sienna Miller out getting her hair done (June 24).
