But one of her latest selfies has caught attention for all the wrong reasons.
The 24-year-old posted a snap to Instagram at the weekend, showing off a very slim frame which caused some of her fans to worry.
One concerned follower said: “Oh god this pic she looks ill, she was looking stunning but this is too far.”
Another added: “You look ill! It's not all about being skin and bone! Curves are sexier, FACT!!”
But some defended the Geordie Shore star, claiming that some people will never be happy no matter how much she weighs.
A particularly riled up fan said: “People moan she's too fat & now moan she's too skinny? she's doing this for herself! not the public! haha!
“She looks slim yes! but she looks amazing & healthy! she is eating! she's just not eating SH*T! She's eating healthy & working out! I’m jelous of her new figure! she looks fab! [sic]”
A source close to the star recently insisted she’ll never go back to her old weight, after going from a size 16 to an eight.
The insider told Closer: “Charlotte is in the best shape of her life. She feels like a different person and has been given a new lease of life. A year ago, she felt horrendous showing off her body on the beach. Now she’s in shape, she says she’s determined never to go back.”
Do you think Charlotte’s fans are right to be concerned?
