Kelly Osbourne flaunts 40kg weight loss in tight black suit

The daughter of Ozzy Osbourne has flaunted her astonishing 40kg weight loss in Malibu, where she wore a rather revealing outfit.

Kelly Osbourne has been seen rocking her slimmest figure yet after losing a staggering 40kg.

The 35-year-old, who recently revealed that she underwent a secret “gastric sleeve” surgery, was spotted wearing a tight black blazer and ripped skinny jeans as she met with a producer in Malibu at the weekend.

Kelly hasn’t been shy about showing off her new fit body and has made a number of public appearances since slimming down.

It was first revealed in late August that Kelly underwent a gastric sleeve weight loss surgery to help her lose almost 40kg.

The news of her surgery came after she shocked fans by sporting a much slimmer look.

Kelly confirmed the procedure while appearing on the Hollywood Raw podcast with Dax Holt and Adam Glyn.

She said: “I had surgery; I don’t give a f**k what anyone has to say.”

The Fashion Police star continued: “I did it, I’m proud of it, they can suck sh*t. I did the gastric sleeve.

“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.

“I want to be very clear about this kind of surgery I had. I didn’t have a gastric bypass.

“The kind of surgery I had … if you don’t work out and you don’t eat right, you gain weight. All it does is move you in the right direction.

“What people don’t realise is, it cuts out this hormone that if you have addiction issues, it stops your craving and it makes you not emotionally eat which is a huge problem for me.”

Kelly additionally had a procedure done on her jaw, which gave her a slimmer face.

She explained: “I had really bad TMJ (pain in the jaw joint). 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.

“I found out it’s called buccal fat. It changed everything on my face.”
