Watch out any girl thinking of dating one of Cher Lloyd's ex-boyfriends ... she may stop at nothing to win him back.
The 18-year-old singer ends up arrested and posing for a mug shot in the new, re-worked music video for her latest single Want U Back after fighting her ex's affections.
The music video has been completely re-shot to appeal to an American audience as the X Factor alum makes her bid for Stateside stardom this month.
