Sharon Osbourne Looks Unrecognizable in Unearthed Photos Shared by Son Jack

Just because Sharon Osbourne has been an instantly recognizable celebrity for years doesn't mean that was always the case.

In honor of her 73rd birthday on Oct. 9, Sharon's son Jack Osbourne took to Instagram to share a collage of photos from the past and present: two pics of Sharon and her husband, Ozzy Osbourne, surrounded by their grandchildren (and in one photo, their daughter, Kelly Osbourne), and two black-and-white snaps of Sharon as a young girl.

"Happy Birthday to the Matriarch and the [rock emoji]," Jack captioned his post.

Jack's followers couldn't get over how much his oldest daughter, 12-year-old Pearl, resembles her grandmother when she was a child.

"Wow your oldest daughter is your mom's mini!!!" wrote one fan.

"Mrs O and your daughter Pearl are identical 😍," agreed another person.

"Wow Pearl looks so much like her when Sharon was young ❤️," noted a third Instagram user.

"Happy birthday Sharon! Your daughter looks just like your mom 😍," declared someone else.

Other fans took the opportunity to send Sharon their best wishes.

"Happy birthday Sharon and thank you for everything you've done to keep Oz going. He was my first concert back in 86 on the Ultimate Sin Tour and been a fan since before that. I hope you have the best Birthday and the most awesome Year ever!!!🤘🏻🎸🤘🏻" commented a longtime Ozzy fan.

In addition to Pearl, Jack shares daughters Andy, 9, and Minnie, 6, with his ex-wife, Lisa Stelly. He shares his fourth daughter, Maple, 2, with his current wife, Aree Gearhart.
