TV personality Kelly Osbourne has doubled down against criticism of her slim appearance since the death of her father.

Ozzy Osbourne’s 41-year-old daughter has been under attack on social media for her looks, with people commenting that she should “get off Ozempic”.

On Wednesday, Osbourne posted a story to Instagram, telling people to “go f— yourself”.

“I’m just here to say, ‘What do you expect from me? What do you expect me to look like right now?’

“The fact that I’m getting out of bed and facing my life and trying to be more than enough, I should be commended for that,” she said.

“For example, you say that I look ill. Well, I am ill right now. My life is completely flipped upside down.

“I don’t understand how people expect me to bounce back and look like everything is just fine in my life when it’s not.”

Osbourne accused people of being bullies and said their “mean comments” were helping nobody.

“They’re just making you feel big and clever and like you’ve achieved something, but all you’ve achieved is being a bully,” she said, adding, “it’s sick.”

The reality TV star, whose life was fodder for viewers in The Osbournes, said her appearance had changed in the decades since the show aired in 2002.

“Another thing that is strange is that you compare photos of me now at 41 years old to a picture of me when I was 18 years old. People’s faces change when you grow older,” she said.

While she had received much “lovely, lovely, lovely” support from people since losing her father, Osbourne said she was shocked at the “disgusting, horrible, mean, rude” things other people said.

“The thing that I find the most disappointing in all of this is that most of the comments are coming from grown ass women,” she said.

“Women that say they’re counsellors, women that are mothers, women who look like they have weight struggles of their own.”

“It’s absolutely devastating that women can’t support other women.

“They’d rather tear them down when their dad just died. It’s disgusting, and I’ve had enough of it. So, go f— yourself.”

Earlier this week, her mother Sharon Osbourne spoke with British broadcaster Piers Morgan about the rocker’s final days. Sharon said her daughter had struggled to eat since her dad’s death.

Sharon opened up about his final days during an appearance on Piers Morgan Uncensored.

“He had told me that he was ­having dreams in the last week of his life. He was seeing people that he never knew,” she said.

“I said, ‘Well, what kind of ­people?’ He goes, ‘All different people. And I just keep walking and walking, and I’m seeing all these different people every night, and I go back there and I’m looking at these people, and they’re looking at me, and nobody’s talking’. And he knew. He was ready.”

Sharon — who married Ozzy in 1982 — also recalled details of their final night together.

“He was up and down to the bathroom all night, and it was like 4.30 and he said, ‘Wake up’. I said, ‘I’m already bloody awake, you’ve woken me up’. And he said, ‘Kiss me’. And then he said, ‘Hug me tight’.

“I can’t help wondering if I should have, could I have? If only I’d have told him I loved him more. If only I’d have held him tighter. And he went downstairs, worked out for 20 minutes and passed away.”

Ozzy died after suffering a heart attack and Sharon “knew instantly” that her husband was gone.

“I ran downstairs, and there he was, and they were trying to resuscitate him, and I’m like, ‘Don’t — just leave him. Leave him. You can’t. He’s gone’,” she said.

“I knew instantly he’d gone. And they tried and tried, and then they took him by helicopter to the hospital and they tried, and it’s like, ‘He’s gone. Just leave him’.”
