Fans of Kelly Osbourne were left stunned this week when photos emerged of her showing off her impressive 85-pound weight loss as she stepped out in a sexy black suit.

The Mirror reported that Kelly, 35, was photographed in Malibu, California on Sunday as she headed to a meeting with producer Jeff Beacher. Back in August, she revealed that she had secretly undergone a gastric sleeve procedure, crediting that in part for her new slimmed-down look.

“I had surgery. I don’t give a f**k what anyone has to say. I did it, I’m proud of it, they can suck s**t. I did the gastric sleeve,” Kelly said. “All it does is change the shape of your stomach. I got that almost two years ago. I will never ever ever lie about it ever. It is the best thing I have ever done.”

She has previously talked about her change to a vegan diet, saying that this is a big part of her shrinking figure as well.

“Once I learned how to work out right and eat right, it’s one of those things that you just have to commit to a life change rather than being on a diet,” Kelly said.

However, this does not mean that she doesn’t miss certain aspects of her life prior to becoming a vegan.

“I really miss eating cheese so today I tried ‘vegan shell pasta and creamy sauce’ aka Mac & cheese… you can not tell the difference,” Kelly explained.

Last month, Kelly’s mother Sharon Osbourne spoke out to praise her daughter for her physical transformation.

“Doesn’t she [look great]?” Sharon asked Entertainment Tonight. “She’s like, she’s unbelievable. Listen, she can do anything.”

During a recent interview on Hollywood Raw with Dax Holt and Adam Glyn, Kelly admitted to getting injections to change the shape of her face in the hopes of making her jaw appear “skinnier” after suffering with TMJ (temporomandibular joint dysfunction).

“One thing I did that changed my face,” she added. “I had really bad TMJ. One of the things they did to stop it was they gave me injections in my jaw. It kinda made my jaw look skinnier. “

“That’s when people started to notice that I had really lost weight because it changed the shape of everything,” Kelly said. “I found out It’s called buckle fat. It changed everything on my face! How the f*** did I not know about this sooner?”
