Kelly's had a difficult time lately battling rumours that boyfriend Danny Cipriani has been texting other women behind her back.
However, she hasn't been staying inside moping. Instead, she's been out with friends looking gorgeous and flashing her trademark smile at the cameras. Always the best form of revenge.
