Kelly Osbourne showcases the results of her dramatic weight loss in black pencil skirt as she celebrates her 40th birthday in LA

Kelly Osbourne displayed the results of her dramatic weight loss as she celebrated her 40th birthday on Friday. 

The TV personality looked nothing short of sensational as she enjoyed a night out at the W Hotel in Los Angeles with her friends and family.

Kelly cut a glamorous figure for the evening as she slipped into a black strapless top with a sweetheart neckline.

The star, who is the daughter of Ozzy and Sharon Osbourne, also wore a matching pencil skirt.

Adding height to her frame with a pair of black heels, Kelly added to her look with a pearl necklace.

Styling her blonde locks into an updo, Kelly completed her outfit for the evening with a black bow.

The star looked in good spirits as she posed alongside her close friend, actor Daniel Nguyen and she was also joined by her mother Sharon.     

In recent months, rumors swirled that she used the popular weight loss drug Ozempic — a medicine for adults with type 2 diabetes — to shed some pounds after giving birth to her son in 2022.

The starlet claimed she had not used the drug back in late April, instead revealing she 'rapidly' lost weight by cutting out 'sugar and carbohydrates.'

'I know everybody thinks I took Ozempic. I did not take Ozempic. I don't know where that came from. My mom took Ozempic,' she explained to Extra at the time.

Despite previously praising the drug, she opened up about her battle with gestational diabetes during pregnancy, which influenced her decision to lose weight. 

'I had gestational diabetes, and I had to lose the weight that I had gained during pregnancy, otherwise I was at a higher risk of actually getting diabetes, which I did not want,' the model claimed.

Kelly also got candid about using special toning treatments, such as EMFACE and EMSCULPT NEO, to sculpt her face and tighten her body.

'I had the baby and my stomach got so many stretch marks, and the skin, it looks like it lost its elasticity,' she shared.

Earlier this year while at Dolly Parton’s Pet Gala she commented on Ozempic, saying, 'I think it's amazing.'

Later in the same interview, she accused critics of the medication and other weight-loss drugs of being jealous. 

'People hate on it because they want to do it,' she claimed. 'And the people who hate on it the most are the people who are secretly doing it or pissed off that they can’t afford it.'

In 2020, she admitted to having undergone gastric sleeve surgery to help her lose 85 pounds.
