Kelly Osbourne debuts new look in London after dramatic weight loss

Kelly Osbourne flaunted her dramatic blond hair transformation after clapping back at critics for commenting on her weight loss.

The “Fashion Police” alum channeled Marilyn Monroe with her chin-length hair styled in voluminous loose waves while attending Juliet Sear’s bakeware collection launch in London on Tuesday.

She glammed up with a bold rose-colored lip and a light smoky eye.

Osbourne, 41, looked chic in a charcoal gray button-up and matching pants for the special occasion.

The TV personality accessorized with black heels, a black bracelet, a gold necklace and drop earrings.

She appeared in good spirits for the outing, while posing for photographers and the woman of honor, Sears.

Osbourne notably dyed her hair blond last year, but didn’t debut a shorter length until January.

Then, in May, she showcased her hair in waves, sharing that Monroe was her inspiration on Instagram.

Flaunting her look in a selfie, she captioned the photo, “I love a little Marilyn look to get this Saturday started!!!!!”

In the past, Osbourne has rocked lavender and bubblegum pink-colored hair.

The actress, meanwhile, stepped out after calling out haters commenting on her dramatic weight loss since the death of her dad, Ozzy Osbourne.

“To the people who keep thinking they’re being funny and mean by writing comments like, ‘Are you ill, or ‘Get off Ozempic,’ or ‘You don’t look right,’” she said via an Instagram video, per Piers Morgan.

“My dad just died, and I’m doing the best that I can, and the only thing I have to live for right now is my family. And I choose to share my content with you and share the happy side of my life, not the miserable side of my life,” Kelly added.

“So to all those people, f–k off.”

The legendary Black Sabbath rocker died in July at the age of 76.
