She raged, "For anyone telling me to 'chill'... The impact bullies have over the internet can lead people to suicide."I can handle the bulls**t. But do NOT f**k with my baby sister. I'm all for peace and spreading love UNTIL you go after a 12 YEAR OLD who did NOTHING to you... So disappointed that after all the conversation about cyber bullying in this world that people would continue to do this to others.” You May Also Like 'Leon Nights' parody about the boss Leon, sung by X Factor NZ winner Jackie Thomas Celebs Before and After makeup Demi Lovato - Heart Attack - the video Become a fan of The Edge on Facebook and on Twitter .
