Kelly Osbourne shows off dramatic weight loss going trick or treating with her son in LA amid Ozempic rumors

Kelly Osbourne showed off her fit figure while enjoying Halloween with her family amid Ozempic use rumors.

The television personality, 40 — who recently celebrated her milestone birthday — was spotted out in Los Angeles with her longtime boyfriend Sidney Wilson, 47, and their 23-month-old son Sidney, dressed in coordinated lifeguard and shark costumes.

The trio was joined by Osbourne's close pal Daniel Nguyen, and another guest who were also dressed according to theme. 

On Thursday, she put on a shocking display as she flaunted her tiny waist and slender legs despite denying use of weight-loss medication. 

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.

Osbourne 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. 

Osbourne and Wilson were first linked back in 1999 when his band Slipknot toured with Ozzfest — the music festival founded by her A-list parents Ozzy and Sharon Osbourne. 

The pair went public with their relationship in January of 2022, and announced they were expecting their first child together just four months later. The love birds welcomed their son Sidney that November.

On Thursday, Kelly revealed that she and her longtime love 'really want to get married' and are planning on tying the knot.
