GEMMA Collins has showed fans just how much weight she's lost - by slipping into a pair of leather trousers. The 39-year-old looked remarkably slim after her three stone weight loss as she posed on the sofa in a hoodie that read: "Kiss me baby." Despite her cozy attire, the former Towie star worked her platinum blonde locks into a soft curly style and sported a glamorous beauty look for the Instagram shot. The GC's impressive weight loss journey has been credited to her following a range of hardcore diets and using controversial weight loss injections. The £250 shots act as an appetite suppressant and help the body turn stored fat into energy. Speaking on Instagram, the star opened up about her controversial way of losing weight and told fans: "They have transformed my whole life with regards to dieting." But despite praising the product on her platform, Gemma was recently rapped for breaching ad rules by promoting the weight loss jab, after she didn't make it clear she was advertising it on her platform. She has treated herself to various other procedures since shedding the pounds, including a hydro oxygen facial back in August. Gemma also had a painful "jawline tightening" treatment to make herself look permanently contoured. She filmed herself getting the procedure and told fans: "Girls, if any of you are trying to contour your face, this is the best girl to do it. "I've got no filter, I've got nothing on my face." The beautician explained: "Basically we are doing a jawline contouring and tightening treatment. There's no needles, it's literally done with a machine."
