Kelly Osbourne reveals the heartbreaking truth behind her sudden weight loss

Kelly Osbourne has responded to speculation about her appearance, revealing that grief after the death of her father, Ozzy Osbourne, has contributed to her recent weight loss.

In a video aired on Piers Morgan Uncensored, the 41-year-old addressed comments accusing her of using weight-loss drugs or looking unwell.

“My dad just died and I am doing the best that I can,” she said. “I choose to share the happy side of my life, not the miserable side. So to all those people, f*** off.”

Ozzy Osbourne died in July aged 76 following a private battle with Parkinson’s disease. Kelly’s mother, Sharon Osbourne, defended her daughter during the segment, saying she “cannot eat right now” and adding that online hate often comes from people who are “unhappy”.

Kelly later posted on Instagram Stories, thanking supporters while calling out the “mean” comments she has received, many from “grown women”.

“What do you expect me to look like right now?” she said. “The fact that I am getting out of bed and trying should be more than enough.”

She said her grief has left her “ill right now” and criticised comparisons between current photos and images of her as a teenager.

Osbourne debuted a new blond hairstyle at a London event this week, where her slimmer frame drew attention. She has long spoken about body shaming, previously saying she received “more s***” for her weight than for her past struggles with addiction.

“We live in a fat-phobic world,” she said earlier this year. “People would say, ‘You are so pretty, why not lose a little weight?’ It was insane.”
