Kelly Osbourne shows off dramatic weight loss as she celebrates 40th birthday in LA

KELLY Osbourne revealed her recent weight loss in a classic LBD as she pulled out all the stops for her 40th birthday.

The Osbournes TV star - who recently denied using Ozempic for her 85lbs slimming achievement - stepped out in a bandeau-neckline garment with buttons up the chest.

The dark fabric, which featured a leather skirt, clung to Kelly's slender frame courtesy of the figure-hugging material.

She accesorized with a black bow pinned in her fresh platinum-blonde locks - after a recent Kim Kardashian hair transformation - and a pearl necklace.

Making sure she kept her elegant style, she finished off with black point-toe heels.

One Word singer Kelly posed by a huge three-tier white birthday cake - adorned with her name and dark bow detail - before cosying up to her mum Sharon.

The former The Talk panelist, who has lost weight due to Ozempic, also chaneled the all-black look with her outfit.

The red-head donned a chic black blazer and matching trousers as the pair enjoyed a cuddle.

Kelly's best pal, actor Daniel Nguyen, was seen enjoying a giggle with the star.

They were all smiles as they posed outside the party venue, this being the W Hotel in Los Angeles.

The reality TV star recently made a joke about her changing shape while on-screen with brother Jack.

Kelly and her Brit brother took to the hot seat with Who Wants To Be A Millionaire? host Jimmy Kimmel.

The brother-sister duo had it easy until the $8000 question.

It was, "Approved in the 1970s to treat high blood pressure, the drug minoxidil was 'repurposed' after many patients who took it experienced what side effect?"

The sibs used their 50/50 lifeline, which left, C: "Substantial weight loss," and D: "Excessive hair growth."

They were still stuck and began arguing with each other.

Kelly curtly said, "I'm telling you Jack, if it were weight loss I'd know."

KELLY'S TRANSFORMATION

The Osbourne sibs are the children of Black Sabath rocker Ozzy and Sharon, 71.

Kelly has amazed fans with her new figure and hairstyle, looking unrecognizable in recent months.

While mom Sharon has openly embraced her own 42-lb weight loss being from Ozempic, Kelly has shut down rumors she's on the drug.

"I know everybody thinks I took Ozempic," Kelly recently told Extra.

"I did not take Ozempic. I don’t know where that came from. My mum took Ozempic."

Kelly has insisted that she lost her post-baby weight by cutting out sugar and carbohydrates. She also had gastric sleeve surgery in 2018.

She's also credited other non-surgical techniques like EmSculot - a body and face non-surgical treatment to "tighten loose skin" after "rapid weight loss."

Kelly, the second-born of three children in the Osbourne family, was in the public eye from the moment she was born.

She was just a teenager when she first appeared on our TV screens on the family's reality show The Osbournes, sporting jet black hair, a hot pink moment, or a bright red hairdo.

In 2022, when chatting about her life with Jada Pinkett Smith on Red Table Talk, Kelly confessed that at one point it got so bad, she had voices in her head saying, "You’re fat, you’re ugly, you’re not good enough, no one likes you, you don’t deserve this, people only like you because of who your parents are".

The never-ending public criticism led Kelly to develop an addiction to painkillers after getting ''a really bad case of tonsillitis'' - which at one point saw the teenager pop in 50 pills a day.

But after managing to kick the drug addiction aside, the reality TV star realised she had ''replaced the drugs with food''.

She admitted: "I just got fatter and fatter... I'm an emotional eater."
