Jack Osbourne's Daughter Pearl Makes a Rare Public Appearance — and Fans Are Doing a Double Take

It was a rare moment that left longtime fans absolutely floored.

Jack Osbourne, the son of rock legend Ozzy Osbourne, stepped into the spotlight at the 68th Grammy Awards after-party on Sunday, 1 February — but he wasn't the only one turning heads. The 40-year-old media personality brought along his two eldest daughters, and fans could hardly believe how grown-up they'd become.

A Family Night to Remember

Flanked by 13-year-old Pearl Clementine and 10-year-old Andy Rose, Jack looked every bit the proud father as he walked into the star-studded event just hours after a tribute was held in honor of his late father, Ozzy.

The sisters wowed in matching polka-dot ensembles, exuding old-Hollywood charm with a playful twist — and the internet couldn't get enough.

Pearl, Jack's firstborn, wore a striking sleeveless white dress covered in bold black polka dots, with a fitted bodice and softly flared skirt. A coordinating necktie tied neatly at her collar added a vintage flair, while sheer dotted gloves, a jeweled clutch, and a swipe of classic red lipstick completed the look.

Her younger sister Andy offered a clever style inversion, donning a sleeveless black dress with white polka dots, a matching necktie, subtle accessories, and a youthful elegance all her own.

'They Are So Grown Up!'

Photos of the trio quickly spread online, and the reaction was immediate — and emotional.

"Pearl is nearly as tall as her daddy! And Andy is a doll! Wow they've grown up too fast in a good way," one fan gushed. "They are so grown up. Very lady like," another wrote.

"I can't believe Pearl is a teenager!" a third exclaimed, while others reminisced over the Osbournes' early reality TV years. The reactions kept flooding in.

"How is this possible? I remember when Pearl was born and it doesn't feel like that long ago 😂," one fan joked, echoing the disbelief felt by longtime followers of the famous family.

"They look very much like him and sooo grown up," another chimed in. "Wow—don't know he had a daughter so grown! 😮," someone else added.

A Granddaughter Born in the Midst of Heartache

From the moment Pearl entered the world, her arrival sent emotional ripples through the Osbourne family. Her grandmother, Sharon Osbourne, was overwhelmed with love as she witnessed the birth of her first grandchild — a moment she later described as life-changing.

Taking to X shortly after, Sharon shared her joy with the world, writing:

"Today I witnessed my first grandchild being born, life changing experience. She is an angel."

Pearl made Jack a father for the first time on 24 April 2012, during his marriage to ex-wife Lisa Stelly. At the time, her arrival marked not only a joyous family milestone, but also a period of profound change.

Only weeks before Pearl's birth, Jack was diagnosed with multiple sclerosis — a life-altering moment he described as a turning point. "So there's this weird association with my life before [being a] parent and then my life before MS," he told PEOPLE in 2016.

A Hands-On Dad With a Firm Yet Gentle Approach

Jack described his parenting style as a balance between fun and firm. "I like to try and ride the line of being fun, but yet mean [when] I say, 'This is how it's gonna be,'" he explained.

Back when Pearl was a toddler, he shared that she had already begun testing boundaries — an early lesson in the challenges of parenthood.

"She's really going through pushing the limits," he admitted. "She's understanding what defiance is, and if she digs her heels in she might actually get her way and what she wants to do versus [listening] to her mother and [me]."

Still, Jack acknowledged that children crave structure, even when it's uncomfortable. "I'm not a big fan of [timeouts and reprimanding]. But I think kids crave it at the end of the day."

Wisdom Passed Down From Ozzy and Sharon

From his own parents — Ozzy and Sharon — Jack learned the value of open, respectful communication. Rather than enforcing authority with a heavy hand, he said his parents emphasized mutual understanding.

"It [was] always a conversation, which I think is really important to be able to have — communicating with a kid on their level versus trying to talk down to a kid," he explained.

Now, as a father himself, he follows a similar approach — firm when needed, but always with explanation and care once "the tears have gone away."

A Close-Knit Sisterhood

As the family grew, Pearl stepped seamlessly into the role of big sister. Jack's ex-wife Lisa once praised her daughter's loving nature. "Pearl's the greatest big sister ever. She's so sweet," Lisa said,

Jack also shared that Pearl loves the outdoors, and he regularly took her camping and into nature, saying simply, "We need that."
