Kelly Osbourne is urging fans to have compassion as she continues speaking out about body shaming.

The singer and TV host, 41, took to Instagram to address comments about her weight loss after she stepped out at the BRIT Awards on Saturday, Feb. 28.

Osbourne, who has been grieving the death of her father Ozzy Osbourne since last year, wrote in an Instagram story, "There is a special kind of cruelty in harming someone who is clearly going through something. Kicking me while I'm down, doubting my pain, spreading my struggles as gossip, and turning your back when I need support and love most."

"None of it proves strength; it only reveals a profound absence of compassion and character," she continued. "I'm currently going through the hardest time in my life. I should not even have to defend myself. But I won't sit here and allow myself to be dehumanized in such a way!"
