Los Angeles: Paris Jackson slammed critics after getting backlashed for not posting a Father's Day tribute to her late father Michael Jackson. After fans attacked the 18-year-old for not posting about Father's Day on June 19, she took to Twitter to hit back, reports aceshowbiz.com. "If you try to harass someone into posting online about a holiday (Father's Day), ask yourself if it is any of your business," Paris wrote. Hours later, she wrote: "Having eight tattoos dedicated to someone overrules a single post about them on a stupid social media account because of a holiday." She also retweeted another user's post which said: "Wait, they are really giving you a hard time for not posting yesterday? Really? How you remember your father is your business." Paris was 11 years old when Michael passed away. She has paid tribute to her father with several tattoos, including a tattoo of Michael's eyes and a group of animals. Previously on her 18th birthday, she revealed a new tattoo featuring the words "Queen of My Heart" in her late father's handwriting.
