Actress Sienna Miller seems to have made it a habit of breaking promises, for the actress has once again broken her vow to quit smoking.
The 26-year-old star made her usual New Year resolution to give up smoking but after just a few days, her promise failed miserably.
A source revealed that the 'Factory Girl' has been making and breaking promises every year.
"She makes the same promise every year and breaks the same promise every year," the Daily express quoted a source close to Miller, as saying.
Miller has already set a record, for her resolution lasted even less than 48 hours.
"This year she's broken her record for her shortest ever time as a quitter, as she lasted less than 48 hours," the source added.
The source also said that the actress blames stress and a desire to do something with her hands for not letting her to give up the habit.
