I don't mind it*, it looks a bit incomplete though, like a patterned rug on her lower-back and bum but it's probably not finished yet. It's her body and her choice. I wouldn't have it but can appreciate other people's rights and choices to do so.
*Not a Cheryl fan, at all.
ETA: I'm really disliking the general comments theme here on DS, that Cheryle had somehow defaced or ruined herself. As if her career and likability rely on her confirming to some generic standard.
