AceShowbiz - Kelly Osbourne, 40, turned heads on Halloween as she showed off her slimmed-down figure while trick-or-treating in Los Angeles with her boyfriend Sidney Wilson and their son. The trio donned coordinated lifeguard and shark costumes, joining Osbourne's close pal and another guest who also dressed according to the theme.

Despite denying the use of weight-loss medication, Osbourne's tiny waist and slender legs raised eyebrows. In recent months, rumors have circulated that she may have taken Ozempic, a drug intended for adults with type 2 diabetes but often used off-label for weight loss.

Osbourne has previously denied using Ozempic, claiming she lost weight rapidly by eliminating sugar and carbohydrates. She has also credited gastric sleeve surgery, which she underwent in 2020, for helping her shed 85 pounds.

Despite her denial, Osbourne has expressed admiration for Ozempic in the past, praising it as "amazing." However, she has also spoken about her battle with gestational diabetes during pregnancy, which motivated her to lose weight to reduce her risk of developing diabetes.

In addition to her weight loss journey, Osbourne has been open about using special toning treatments like EMFACE and EMSCULPT NEO to enhance her appearance.

Osbourne and Wilson have been dating since 1999 and welcomed their son, Sidney, in November 2022. The couple has expressed plans to marry in the future.
