Charlotte's made no secret of the fact she has had lip fillers in the past, but it sounds like Louise is not such a fan. In fact, she has now said that she thinks it's "sad" of Charlotte to alter her lips...
Speaking to new! magazine, Louise had her say on Charlotte's use of the cosmetic treatment and said: "It's really bad - and sad. I've never met her, but it's not a great image to portray to younger fans. Geordie Shore has such a big audience and she was so cool, her personality was everything, and now she looks totally different."
Charlotte, meanwhile, spoke to the same mag and hit back at Louise for her comments.
She seemed surprised by what Louise had to say about her, and fired back in response: "She said that? I'm not really that bothered. People do things to alter the way they look every single day.
"Louise Thompson puts make-up on her face," Charlotte said. "That's quite sad. Is she not happy with the person she is? Bore the f**k off."
Charlotte also revealed that the last time she had her lips injected with filler was back in January, earlier this year.
It's not the first time the 26-year-old has come under fire for her lips, and recently Charlotte shrugged off any criticism by sharing a selfie that focused heavily on her pillowy pout.
It left fans concerned, with one user commenting on her post: "They look only painful and like they are about to blow up." Another added: "It looks like she's had an allergic reaction."
Others made sure to support Charlotte and told critics that it was her choice. They replied: "Leave Charlotte alone! It's her body, her choice." "Who cares what others think as long as you're happy."
Charlotte, meanwhile, seemed to predict the star her lip selfie would cause and added the caption: "Cue the lip police."
