The X Factor judge has 1.7 million followers on her @CherylOfficial page but now, unless she accepts you as a follower, you won't be able to see what she's been posting.
Cheryl's new bio explains her decision. It reads: "If you're a negative person, swerve. You have no place on my page. Good vibes only."
Fair enough, right?
The 32-year-old former Girls Aloud singer has often spoken out about disliking the negativity that comes with social media. Earlier this year, she responded directly to one troll who branded her a "bag of bones" after seeing photos of her at the X Factor auditions.
Cheryl put the Instagram trolls to one side over the weekend to join her former bandmate Nicola Roberts in celebrating Nicola's 30th birthday in London. Kimberley Walsh was also at the bash.
