Ever since new princesses were crowned and born Celestia's been putting less and less effort in her figure and simply let herself go. Luna; being for a healthy lifestyle opts to tell her sister enough is enough. But the question isn't should she tell Celestia, but can she tell her?

DISCLAIMER: Don't take this fic seriously. I just wanted to write for the fun of it.
