It all began when she shared this tweet, letting her teen fans know that they don't need to worry about whatever their exam results happen to be today.
She's shared this funny anecdote about Pitbull before for similar purposes.
But on Thursday morning one particular follower used it against her, and trolled her by responding: "And remember Scarlett Moffat made money by watching tv on tv. Anyone can be successful no matter how brain dead."
So she served this perfect clapback, revealing that actually she is very well educated thank you very much. But she added that the most important thing to succeed in life is to "be kind" and "work hard".
Then she went back to helping ease her followers' concerns over any results they might get, repeating her earlier sentiment about working hard and being kind.
