AceShowbiz - Kelly Osbourne and Jack Osbourne turned heads with their recent appearance on "Who Wants to Be a Millionaire," where Kelly's weight loss journey became the talk of the night. Competing on the game show for charity, the siblings entertained both the audience and host Jimmy Kimmel with their banter and candidness.

The duo managed to navigate most of the questions with ease until they encountered a challenging $8,000 query, "Approved in the 1970s to treat high blood pressure, the drug minoxidil was 'repurposed' after many patients who took it experienced what side effect?"

With options narrowed down to "substantial weight loss" and "excessive hair growth" through the 50/50 lifeline, Kelly wittily quipped, "I'm telling you Jack, if it were weight loss I'd know," drawing laughter from the audience and a reaction from Kimmel.

Fortifying their choice with the "Ask the Audience" lifeline, they correctly selected "excessive hair growth." However, they struggled with the $64,000 question, ultimately walking away with $32,000 for the Race to Erase MS charity, a cause close to Jack, diagnosed with multiple sclerosis in 2012.

Beyond their game show performance, Kelly has been in the spotlight for her dramatic weight loss. Dropping 85 pounds, she credits her transformation to cutting out sugar and carbs, as well as undergoing gastric sleeve surgery in 2018.

"I know everybody thinks I took Ozempic," Kelly told Extra, dispelling rumors about using the weight-loss drug that her mother, Sharon Osbourne, has openly used. She attributed her post-baby weight loss to lifestyle changes and nonsurgical treatments like EmSculpt to tighten loose skin.

Kelly's openness about her weight loss journey has resonated with many. On the "Hollywood Raw" podcast, she stated, "I had surgery; I don't give a f*** what anyone has to say... It is the best thing I have ever done." However, she emphasized that surgery alone isn't a cure-all, stressing the importance of maintaining healthy habits.
