The famously curvy star refused to be bothered by internet remarks on her size, taking to the network to share a photo of herself captioned: 'Wore McQueen and ate a burger in-between #Curves #Kinngit #NoTimeforHaters.'
Twitter users suggested Kelly had put on weight recently, after spotting her in more covered up outfits of late. This comes despite the fact Kelly is mainly pictured heading to and from the gym in LA with her fiancé David Macintosh.

Price added that she thought her campaign shots 'misled the consumer' because they seem to show a noticeably slimmer version of Kelly to the one captured by the paparazzi.
