Miley Cyrus shows off her renegade side with her newly chopped locks and cigarette Tuesday. Photo agency X17 caught the 19-year-old smoking out the car window of her Mercedes SUV as she was dropping her fiance, "Hunger Games" star Liam Hemsworth, at the airport. (For the record: Hemsworth smokes too.)

Cyrus debuted her new, peroxided haircut in mid-August -- just the tip of the iceberg when it comes to her rapidly changing physical appearance. The star's slimmed-down figure has been frequently documented, thanks to Cyrus' repeat visits to the Pilates studio and running routine. Earlier in 2012, Cyrus vehemently denied having an eating disorder, saying on Twitter that her weight loss was in fact due to a "gluten and lactose allergy."
