Here's a young Jen with her father, John. In case you didn't know, he's an actor who has been in the industry for decades.

He played Victor Kiriakis on Days of our Lives since 1985. Jennifer's late mom, Nancy, was also an actress.

She was a bad gal right from the start. Just look at that mean (yet adorable!) mug.

In case you want more young RiRi, check out the star's lookalike. The resemblance is absolutely insane, it'll hurt your brain.

Oh, my! How adorable was she? "vibin since 04," she captioned the pic.

It makes us wonder two things: one, she was blonde growing up?? And two, she definitely could have gotten into acting sooner!

Who knew that this little cutie would become one of the richest actors in the world, and one of the strongest too?

You'll see more of him as a kid in Young Rock, the new show about his life.

We can't with this. IT'S TOO CUTE. The rose tattoo. That sass.

"Keeping this energy as I step into my 23rd year of life, thank you for all the love," the Euphoria actress captioned this on her 23rd birthday.

This photo couldn't be more fitting since the actress recently tackled playing the Grand High Witch in Robert Zemeckis' The Witches.

The clown hair underneath is a bit of a head-scratcher, but we'll let that one go.

This picture proves that America's Sweetheart was always so sweet. It also shows more of the resemblance between her and her famous niece, Emma Roberts.

Now that Emma just had her first child, we're sure the family resemblance will continue.

Back when she was the picture of innocence! Here she is holding her baby sister, Noah Cyrus.

Since Miley smiled so much as a kid, that's actually how she got the nickname Miley! (Her real name is Destiny Hope).

"WHO’S GONNA TELL HER SHE’S THIRTAY NOW" the "Willow" singer wrote on her 30th birthday.

It's crazy to think that this adorable little girl grew up to completely dominate the music world. Like her recent Album of the Year Grammy award.

In signature Chrissy humor, she captioned this sweet pic of her and her mom with this: "I did not choose the perm life. The perm life. Chose me."

The two are still super close, as Chrissy's mom, Pepper, lives with her.

She's been serving lewks even before she became a huge supermodel!

Now that the model has a daughter with Zayn Malik, we can't help but wonder what she looks like and whether she'll look like Gigi at this age.

The moment she entered this world, a star was born.

We've had the privilege of basically watching her grow up since she got her career started on The Mickey Mouse Club when she was only 11.

So precious!

The singer has always been super close to his mom.

He's taken her to many award shows and she even allowed Ryan Gosling to live with them when Justin and Ryan worked on The Mickey Mouse Show together.

"I’ve always been a summer girl #tbt," she captioned this sweet pic of her on the beach.

We can also see how much her daughter, Apple, takes after her, as the 16-year-old is the spitting image of her mom.

This is ICONIC.

The singer proved that she was just like all of us growing up when she shared this hilarious throwback.

The star's dreams came true when she got to meet them while they were on tour!

"Wait, I’m trying to remember—was I ever Prom Queen? #no 🤓#nerdslaughmore," the 13 Going on 30 star captioned this pic.

It's proof that she's always been so silly — and we love her for it! Those glasses are something else.

"Whenever I have the inclination to cut bangs again, I’ll just look at this pic. Thanks Mom!" the This Is Us star hilariously captioned this throwback.

Now that she has her own little one, we're sure she won't make the same mistake!

Since the "Bad Guy" singer is only 19, this photo must have been taken only a few years ago.

But it's not any less adorable. It goes to show that she's always had a huge crush on Justin Bieber.

Now that the iconic singer has three children, it's clear to see that they mainly took after her husband, Jay-Z in the looks department.

That's alright, though, since we'll always have this adorable picture of baby Bey!
